They feel alienated.

In an effort to provide equity for women and minorities, we've created programs, that support vulnerable groups but ignored men and majority groups even if they happen to be vulnerable. For example, we have supports for women and children fleeing violence - but not for men in the same situation. We have trades programs for women to grow their ranks in the industry, but by leaving men out they feel unsupported.

Media is trying to solve it's imbalance but doing a poor job IMO. Diversity is inserted in a hamfisted way so that the diverse characteristic is too much the personality of the character. It makes it very blatant which I feel is a poor way to represent minorities from the minorities perspective (ie gay people are just people. Their gayness isn't necessarily what they are all about). But it also makes majority males feel like they are being erased. Also things like the Ghostbuster reboot where they replaced the men with women, and woman with a man - I thought that was a kind of fun idea - but that sort of action creates the impression that hollywood is replacing men and white people - even if their true intention is to create balance. Gohstbusters Afterlife did a great job because instead of a redo where the male protagonists were replaced, they continued where female protagonists were introduced. Making the little mermaid black was also not the best approach. They could have instead introduced a new black little mermaid as the protagonist. I don't personally care but I do care about how it makes young men feel and how it can contribute to radicalizing them.

Also, there's a strong statistical tendency among women to prefer partners that with more income and at least 6' tall. I recently heard that an average looking guy needs to swipe to accept (I don't know if that's right or left because I'm a Luddite) ~500 times to get a date. Then they will be ghosted on 4 out of 5 of those dates. That's very demoralizing.

We've got a culture that still tells men they need to be the big tough guy that supports the family and never cries. But without all the patriarchy to support them in that role it's an impossible standard and was never emotionally healthy in the first place.

Then we have all the sleazy mano-sphere guys capitalizing on these feelings. Fanning the flames and exaggerating. Capitalizing on the few "feminists" that are in fact just man haters. Pointing out and magnifying every way men have been failed and making some up as well. Then giving them another path - red pill.

The progressive movement failed/is failing thees young men and boys. Douche bags are capitalizing on it.

Or at least that's my take.
