The Greatest Generation begat the Baby Boomers
The Great Depression taught the Greatest Generation that being a pussy means death, while World War II taught them that exposing your emotions to the enemy meant death. There was simply no time for them to complain about shit, because they were too busy trying to survive to do any of that. That's why back then, men were real men, women were real men, and children were real men. Even degenerates like Ed Wood were real men; while killing Japs in the Battle of Tarawa, he wore women's bra and panties. But the bitterness of the Great Depression, World War 2, and the Cold War ensured that the Greatest Generation would try to raise THEIR children—the Baby Boomer Generation—with the same level of harshness they grew up with.
The Baby Boomer Generation, on the other hand, while still raised properly, hated the fact that they were raised so harshly. Their parents from the Greatest Generation never took their kids to a baseball game, told them how well their artwork looked, etc. All they did was complain about their kids whining about shit like toys and crap... which was nonsense as far as the parents were concerned, because a roof over their head and food on their plate was far more than any of them had during the Depression. Toys? Baseball?? I don't give a shit about your fanfic about Howdy Doody meeting Captain Kangaroo. Just be glad you aren't picking sand out of your food, you ungrateful little assholes. Thirsty? Drink your spit. Oh, and I don't want to see you playing with that nigger kid from across the street anymore.
Worse, because of the growing influence of Feminism, pediatricians like Dr. Spock, the growing shift of jobs away from rural areas and towards urban areas (and with jobs went the family), and even television, it became harder and harder for the Fathers of their Baby Boomer children to be positive male role models for their children, as well as instill upon them what it means to be a Man. Whereas, in the past, when the whole family was involved with, say, maintaining the family farm, or were all home schooled, this provided equal parts of positive male and female role models for the children. But because of all the changes happening in post-War America, the Father was simply not around to teach their children much of anything anymore, not for lack of trying. Therefore, young Baby Boomer boys simply lacked positive male-role models, as they were growing up either around their Mom (who ran the house when Dad was away), their teacher (who was usually a woman), or their friends (who were just little kids). This situation was magnified by television, with shows like I Love Lucy and Leave it to Beaver depicting home life as run by their mothers and usually devoid of their fathers. This undoubtedly created problems later on down the road... but we'll get to that later.
Of course the Baby Boomer generation dealt with it, because they didn't know they didn't need to. The 1960's eventually came, and started filling the heads of the Baby Boomer generation with Peace, Love, and Happiness. Then with the Civil Rights Movements of the 60's and 70's teaching the new generation about fairness and equality (while at the same time also teaching them about how white men were the cause of EVERY SINGLE PROBLEM EVER in the history of the WORLD), the Baby Boomer generation ultimately decided that, when they have children, they're not going to be the stoic brick wall their parents were, but would instead be their children's best friend. When the time comes, it'll be the Baby Boomer's chance to raise their children right, with the right music, right thinking, right history, right everything. This time they WILL take their kids to a baseball game, they WILL tell them how well their artwork turned out, they WILL let them make friends with non-white kids. In fact, their kids get a TON of awards for their artwork and achievements, just to make up for the ZERO awards they got when they were a kid. The children of the Baby Boomers will get everything the Baby Boomers never got.
The Baby Boomers begat The Gen X-ers, Millennials
So in comes the 70s, and the earlier Baby Boomer Generation finally started having children: either Generation X—born between the 70's until maybe 1983—or Millenials—born between 1984 until the the 90, with the Generation Xers themselves filling in the second-half of the Millenials. Either way, the Baby Boomers gained more and more seniority in their respective workplaces around the same time, such that, by the time the post-Gen X generation, the Millennial Generation, reached school age, the Baby Boomers had completely taken over the positions of authority their parents and grandparents once held. No longer did the Baby Boomers need to challenge the authority of their parents as children or as young adults, THEY were now THE Authority, and so now it was THEM who decided what would be taught and what would be expected from others. In due time the Baby Boomers make good on their promises to be far more friendlier to these children than their parents ever were to them. The Baby Boomer Generation relished in the joy of finally being able to teach people that it's OK to cry if you got a little sliver playing in the tanbark playground, and nobody would question it. And as they got older, the Baby Boomer Generation—sometimes in tandem with the Gen X-ers—taught these children more hippie and feminist values, like how it's OK for a male to cry, that there is NO EXCUSE to hit a woman, that one should stand up for their beliefs, races and genders were equal (though non-whites are more equal than whites) and so forth and so on. And at the end of the day, the Baby Boomer Generation were happy that the children were finally being taught the right thing.
Unfortunately, none of those lessons were tempered by any kind of common sense (y'know, like, it's OK for a male to cry in PRIVATE and not as a means to achieve a goal, that if women are equal to men then there's just as many reasons to hit a woman as there are for men, etc). Worse, where as the Greatest Generation almost completely lacked any positive doting behavior, the Baby Boomers were TOO doting. Years of being told that they were perfect in every way, that their artwork was simply ALWAYS award winning, and graduating kindergarten was worthy of celebration started to mold the young Millennial's minds into thinking they could do no wrong, that everyone loves them, and authority is nonexistent. All of this was magnified by decades of a lack of positive male role-models and the realization that they didn't have a clear idea of what it meant to be a Man... and although they were there for their children in ways their parents were, this became a case of "the blind leading the blind": how the hell could a generation who knew little about being a Man raise a new generation of boys to become Men? There was no answer... and thus the Baby Boomer parents felt that, as long as their boys and girls were at home watching Care Bears and My Little Pony G1 (but not G.I. Joe because that was too violent) and not out smoking crack or whatever, then that was enough to be a good parent. And so it's no surprise that, as the Millennial Generation grew to adulthood, they simply became the world's newest generation of pussies.
The Millennials begat no one
Of course the real world is far different than the world that the Baby Boomers and Gen X'ers raised the Millennials in, which years of Care Bears did not prepare them for. Everything you do is wrong, nobody loves you, and authority is everywhere. This is exactly what the Greatest Generation learned, and taught their Baby Boomer children... but in the process of tossing out EVERYTHING their parents taught them in lieu of "more correct" rearing (among other things), the Baby Boomer Generation basically left out those lessons when raising their children. But whereas the Gen X-ers at least still had their Greatest Generation grandparents to give them a different outlook on life (at least whoever was left after years of social drinking and smoking gave them all liver disease and lung cancer), the Millenials had no one left to turn to. Now, these Millennial adults are being sent into the world without the proper tools to deal with shit, and in turn have simply become gigantic pussies because of those missing tools. But hey, at least they know that there is NO REASON to hit a woman, right?
Now this usually happened with white people, as pretty much all generations of non-white people to this day still have to deal with enough bullshit in life to temper them enough and prevent them from becoming gigantic sissies. Like, black folk—save for the very most recent #BlackLivesMatter generation—had to deal with racism (and white people trying to latch onto them for some political end), Asians were too busy escaping communism and other leftist regimes to support American-style liberalism much, etc. But for white Millennials, who had a pretty easy living as there was nothing left in life to temper them like their grandparents during the 1930's and 40's (and, no, marching against the Iraq War, joining an Occupy collective, and tweeting #BlackLivesMatter doesn't count), and because their Gen X-er parents and Baby Boomer grandparents left them ill-equipped to deal with the realities of the real world, while also being over-burdened with tons of white guilt, the conditions were such that an average white Millennial male devolving into a nu-male was almost inevitable.
And, that's where we are now: we have an entire generation of pussies who are a complete 180 from the Greatest Generation. Their great-grandparents are rolling in their graves seeing their male descendants acting concerned about how being on the receiving end of their girlfriend's strap-on may make them feel "unmanly".
