Young men are much more likely to be non-conforming to sexist cultural/gender norms and stereotypes, which often leads to them being ostracized more by general society and makes it easier for grifters (like manosphere influencers) to take ahold of them and radicalize them with alt-right and/or extremely misogynistic beliefs.

There are plenty of amazing feminist role models, but the right's form of propoganda is so much more enticing because it tells you that everyone else is the problem and you're superior to others, rather than ask you to give a shot at understanding reality like leftist influences do. That goes with anything on the right, fascists are a lot more motivating and good at gaining/rallying radical supporters because it's so much easier to get people on your side if you're allowed to lie about everything. So naturally, impressionable – and extremely vulnerable and emotionally volatile – young men gravitate towards the extreme negative influences due to how our society and education is poorly set up to prevent that.

And in this case how sexism and toxic masculinity is deeply ingrained into our society that so many of these young men are made to feel like they're "not real men" by those around them, it really pushes them towards this even more. Rather than reject the idea of a "real man" or a "real woman", they embrace them even more and convince themselves that they are the realest men, and OTHERS are pathetic.
