I'd say misandrism isn't really as "mainstream" as it used to be a few years ago. Tumblr used to be misandrism central and now you have posts like these. Even now when someone makes sexist comments about men, a lot of the time they happen to be TERFs, further demotivating new people from agreeing with them.

Yeah, currently you can still find misandrist groups, but they are either confined to twitter (either crazy twitter randos or influencers) or to niche communities that have isolated themselves from the world.

Other than that, there's still the ever present sexist jokes, stereotypes, etc against men that have ingrained themselves in society, but also seem to be dying out too as new generations grow. I wouldn't really consider it a rising problem unless there is some female Andrew Tate brainwashing teenagers on this side too.
