As a man, with many male friends, and having grown up deeply entrenched in aforementioned culture.
Id put it at genuinely around 90% outright ignorance.
Schools just literally do not teach this, parents dont teach it, for a lot of men they never actually get any education on the manner.
Period.
So the only education they get is internet influencer propaganda of the Andrew Tate garbage variety and that is basically all they have to work with.
So lets not pretend its terribly surprising when young men grow up in those conditions and go on to become awful individuals, what exactly did we expect to happen?
