I'm generalizing here, but men's lib looks VERY different to women's lib. Women started from a position of very low power, liberation was nearly a continuous improvement for all but the most privileged women.

Men's lib requires first giving up a lot of patriarchal power before gaining the benefits of men's lib, which in my opinion far surpass those of patriarchal power. There are a lot of barriers to this. First, most "online" feminists talk only about giving up patriarchal power. This feels hostile to most men and has bolstered misogynist influencers like tate et al. Second real life men and women are typically both complicit as men in enforcing patriarchal views of what a man is supposed to be. You can see experiences of men crying or expressing real emotion in front their prospective significant others as a prime example of this. Third there is no easy to access popular description of the benefits to men of men's lib. There are great examples, but they aren't as culturally relevant as patriarchal influencers yet.

The path to men's lib is complex and has very different challenges than women's lib. I think we're getting there, but it's certainly a slow process and at this time I think the counter reaction is more prevalent and popular.
