[edit: I thank everyone for their comments and time. A lot of very interesting opinions and view points. Unfortunately also a lot of things that went away from the actual answer. So I’m thinking maybe this thread can be closed without deleting it?]

But so far, I’ve only heard people say that it’s stupid, that it’s not a thing, that it’s men’s own fault etc. But I’ve yet to understand where that criticism comes from. I don’t want to start a discussion on whether or not it’s real or not. I just want to understand where the critics are coming from.
