Today, today it's culturally acceptable to ridicule, scorn, and otherwise attack men and manhood; to portray men as arrogant, abusive, and controlling. The word 'masculine' is now a derogatory term that means the same thing as 'toxic'. "Men are trash".
The message is that to be a man is to be lesser, or irrelevant, or harmful to society. That there's something shameful about being a man.
"There's nothing wrong with taking men down a peg or two; after all, they rule pretty much everything". Yeah, now what about the overwhelmingly vast percentage of men who will never have a management position or hold office? Whose life is just mediocre? Is it also okay to tell him he's toxic trash?
And sure, the proper response is "don't listen to the garbage". Doesn't mean it's okay to spew garbage.
As for entertainment media, it's a shit-show on both sides -- women and men are both horribly stereotyped.
