It seems to me that in many cases the answer may be "what's the alternative?"

For example, if someone doesn't know how to find a girlfriend, then PUAs are the only game in town.

Until viable alternatives are presented I suspect that men will keep going with what's available.

The salient point of an identity group is to be angry at the other groups. This is true of all the groups, and is a very important vice to avoid. It's alluring in a way that people don't have very good defenses against.

Thing is though, whenever they do do something - like say, organising a group to discuss their problems - they get attacked, ridiculed etc. in a way that no other group ever does today.

At least https://www.reddit.com/r/MensLib/ takes a more enlightened approach.

Ditto for every identity group.
