Because it was created and used by elitist pricks who liked sticking their cocks in young boys,
Aristotle, pretty much all the Roman Stoics and most philosophers in general think highly negatively of homosexuality and pederasty. The fact that you are too dumb to even read any of them before you come to such outlandish conslusions about this is proof enogh that you are a normalnigger that gets rightfully insulted when you are called out for living a substandard life.
and now it's being used by the actual dregs of society who see their lack of employment, romantic, sexual and social prospects as a sign they're above the rest of humanity who have jobs, spouses, children and normal, good lives.
That's like saying "X is wrong becausw Y is a degenerate". And? That doesn't answer X's salient point that most people are basically retarded and not really wise at all. Also speaking of X, press X to doubt. If people were living good lives like you described, social alienation, a lack of passing down traditional and useful knowledge and wealth to the next generation, bad attitudes towards love and romance and just the societal degradation you can plainly see today wouldn't be the norm. It's obvious that people know how to.put up a front about how they live their lives, but that doesn't translate tl moral goodness or wisdom. There are (a lot of) evil smart people and nice simple folk, but most people are rather morally and mentally inept just judging by how sick society is today.
The people who seriously start using phrases on the same vein as "sheeple" should be mocked.
Sheeple is a gay term, but most people act like sheep and follow trends. Shit like pet rocks, fidget spinners, the popularity of sportsball and modern video games in addition to a lot of politics and religion relies on people being willfully mindless and just going with whatever is put in front of them. There is a fundamental need to fit in within all people, but if you a lot of people just do shit because it's popular not because it's good or makes sense. It's the driving force the consumerism of today: consume a product without thinking of its long term value or something you could create with it. It's why people go to college to get degrees they don't need. Frankly, if you don't want to be called a sheep, don't act as mindless as one. Sure go with the crowd when it makes sense and it is to your benefit, but don't just go with the crowd just 'cause.
All I can take away from your post is that you are personally insulted because you act like a complete and utter normalfag (which you confuse with a functional human being who cab express his whims apart from the crowd just as much as within it to maintain and even increase his happiness) IRL and being called out like that hit a nerve. Then you brought up mentally ill incels (who aren't even that big or the only group mocking people for choosing to be comolete and utter normalniggers instead of actual human beings) and called basically every philosopher that built the Western world a faggot (even though most of them were opposed to it).
Basically, you can't tell the difference between being a normal, functional human being who has a diverse set of interests and goals in life and a normalfag, who is basically a cog in a machine out of their own choosing. They are not the same thing. A normalfag like you is a pathetic shadow of a person and normaling mediocrity is not a good thing, even if objectively worse off retards rightfully call out normalfags for being pathetic (even though the irony in that case is palpable).
