Evolutionarily, humans are a very male-focused species when it comes to reproductive stress, almost all the selecting factors, except the ones that have an effect on all species like disease, childhood mortality, predation, starvation and such, only impact men. Only male humans compete for dominance, only male humans hoard resources, only male humans wage war against other tribes, if a male human fails at any of these, he will not reproduce. This is not easy at all, which is why investigation of the Y chromosome shows a lack of diversity that suggests only ~20% of men who ever lived successfully reproduced.
There are almost no selecting factors placed on female humans in comparison, if they can survive to adulthood, they are basically guaranteed to reproduce. There are a few things they could do to fuck it up though, namely: Pissing off the group. Probably the only thing a woman could do to squander her chances of reproduction is to piss off the collective/tribe, which is why women have evolved to be extreme conformists. Men, on the other hand, have not evolved to be this way. Conforming is not a good reproductive strategy for men, because historically, there was no such thing as monogamy, and the alpha of the tribe would get exclusive reproductive rights with all the women.
This is why men are more likely to rebel against authority. Challenging the alpha, or going off on your own, might very well lead to death, but conforming and submitting to the alpha means you will never reproduce. This is also a good explanation of why incels exist: Not getting pussy, for a male human, is darwinistically the same as death, and they will do anything to get it, because survival is pointless without reproduction, no sex is the same as no food or no water. That explains the male propensity for risk taking, as reproducing was an all or nothing type of deal for them.
Any kind of cultural shift is at its core powered by women, Hitler won the German election because of women, women were crucial for the success of the communist revolution in Russia, women were the main supporters of prohibition back in the 20's, early Christian converts in the Roman empire were mostly women and homeless people, trannyism started on Tumblr back in 2013, and Tumblr had a userbase composed mainly of women. look at any bad (or good) thing that happened in history, and you'll probably find that at some point, it was up to women to either make or break it. This is because women are evolutionarily tuned to always go along with whatever the culture tells them to, their monkey brain rewards conformity with dopamine because that's the kind of behavior that was selected for. They take on whatever traits are considered desirable in the culture they live in, this is simply because that's the most effective strategy for successfully reproducing. Avoid pissing off the group at all costs.
You can also explain why almost all girls have mental illness with this theory, too: It's because western society is mentally ill.
