I couldn't believe my eyes seeing this advice to teach young boys to hit girls so as to restore the boys' self esteem and pride.
This is the kind of toxic belief that shouldn't be allowed to proliferate here and yet is embraced with open arms by other users.
That boys can only regain their pride and self esteem by hitting girls leads directly to more violence against women and girls.
I have seen the other comments disagreeing with your take that handling a bully who happens to be a girl goes back to misogyny, yes, because you focus on "teaching a boy to use violence against girls is bad" while refusing to deal with the initial violence and are also completely blanking on the self defense part. How should a boy protect himself against a girl who's hitting him? And no, I am not saying "punch back duh". I agree that actually karate classes will teach a 4 year old to avoid getting hurt and keep control and will, in fact, boost his confidence, just not the way the other asshole person you were responding to thinks, and punching back won't go well, short term or long term. The other person may be an ass thinking "they're kids, it's totally fine to hit a girl", but learning how to handle a violent bully, girl or not, is not misogyny.
