I find it interesting how you frame the cultural drift as men falling "behind". I assume you're speaking about politics? I don't know what other aspects of culture that have the genders diverging.
A growing segment of young men increasingly embrace violence, conspiracy theories, far-right politics and machismo in general. Women can tolerate and even embrace a lot of male-coded things, like sports and cars and video games, but do you really expect them to embrace the manosphere or Trumpism? Not to say that this is universal - but there is a clear trajectory and we see it throughout the developed world (see: South Korea).
South Korea seems like a bit of an outlier, in the other countries it’s the women who are strongly moving left while the men show a weaker drift towards the right. So it doesn’t seem accurate to frame the divergence as men becoming far-right fascists. Would you take offence if I said women are becoming Stalinist communists? Neither framing seems accurate to me.
What I think is happening is that women are broadly swayed by social issues and men are more likely to be against mass immigration and focus more attention on the economy. At least that seems to be the case in my country (which isn’t on the graph). A small minority of men buy into the Tate far-right manosphere but I don’t think that’s responsible for the entirety of the shift, let alone the entirety of the shift on the men’s side.
Young men would not feel so alienated if progressives and social media didn’t keep telling them they are violent rapist scum too dumb to think for themselves. Their choice for role model is a society that despises and blames them, or hucksters despising and blaming the other side. Who is young Timmy gonna listen to?
If kids flock to Andrew Tate, the problem are not the kids, nor their gender, but society as a whole must have fucked up enormously and failed 50% of the human population.
Generalising comments like yours ruin lives and you should feel ashamed about it. Sadly, you can find them on the front page of any left-of-centre newspaper.
Progressives talk about simple real world fact that rape exists and is bad. Rape predates Tate.
But when there is sexual avuse or rape scandal, conservatives effectively argue that rape is normal and real victim is the rapist. They are the ones who push them towards Tate, by making his argument.
It is all older generation who see raping as positive thing for hard profile position. Who enabled and helped abusers for decades. Young just learned from them.
