Not all men. But...men.
Okay, hear me out though.
The problem isn't men exactly, it's that there are too many men. 50.2% of the human population is male (except where sex-selection abortion is used to skew - for example, India is at 51.6% male). We don't need so many. 30% would probably do, but we would miss them. Still.
99% of rapes are perpetrated by men (91% of victims are female). 89,000 women were killed by intimate partners in 2022, the same year that 88% of all murders in the U.S. were committed by men. This is true across crime types - men commit more crimes in every country, across all kinds of crime. Male humans are largely involved in, and pushing for, war, and the making of war machines. Males on the whole enjoy and tolerate a lot more violence than females.
Males of the human species are more prone to violence due to their hormonal makeup and the larger size of their bodies, making them threatening to smaller people and creatures, to the point where many would prefer to meet a wild bear than a random man alone in the woods. Within our cultures, men are also likely to support oppressive structures that favor them, and ignore social factors while favoring economic factors in voting. Male humans make poorer communicators than female as leaders in both corporations and non-profits, as well as government. They have a harder time controlling their emotions of anger and shame, and accessing their empathy and gentleness. Given all of this, it's hard to understand why anyone thinks they should be in charge of everything.
Males are generally less involved in child care or community building, less likely to volunteer, and even other men don't trust the self control of the average man enough to want their daughters or sisters wearing low-cut tops to a sports bar and leaving alone in the dark.
Everything I've said is founded in data that you can find easily by doing a search. These are generalizations but they are also true, based on reputably-researched facts, and few people would dispute the ideas based on their own experience of the wide world of men.
But NOT ALL MEN, for sure, even NOT MOST MEN, we know that. I love my men!
Really, it's the QUANTITY that is leading to problems. If 80% of men are not a danger and believe truly in equality and strive to live as Good Men, and men are 50.2% of the population, then about 10% of the population are a problem to peaceful society. But if men were only, say, 42% of the population, there would be numerically fewer assholes (8.4% of the population) AND the balance of power would be naturally shifted to reduce patriarchal power. Men are bigger, stronger, and the power structures of society still favour them, despite the meagre attempts to balance (labelled reverse discrimination). Reducing the male population percentage over, say, a generation or two, would naturally lead to a subtle shift in the way masculine and feminine values play out in society.
Gene-tinkering seems like the future anyway, right? Might as well think about it. Society would probably function just fine with a smaller percentage of males, and maybe we'd have a better chance, as a species, to teach them more self control when young, to overcome their hormonal over-stimulation and proneness to violence, if they weren't the default "majority" of every situation.
We know we don't need 1:1 for the species to continue. One man can father kids from multiple women at once if everyone wants (and sometimes when they don't), and they do that, regardless. Not all women need a partner - even if they did, it's not a 1:1 relationship in the population in that sense anyway.
Men are important in society, but they have their challenges physically and socially that would make having fewer of them seem beneficial to the overall peace of life. It's surprising we haven't evolved in that direction, but since we have the technology now, it wouldn't take everyone to make it happen. Just a percentage of new parents skewing female in the embryo selection every year could do it.
A female-skewed population might just achieve world peace in time for my grandkids to fry from global warming. Maybe we could even solve some of the issues and put that future off indefinitely, instead of diverting all our world's resources to war machines and the hoarding of a few sociopathic billionaires. Mostly men.
Just a thought.
A passing thought. Don't crucify me. Wait, that was men, too.
