I saw a short video the other day about a woman saying "alright we'll just call men ~males~ from now on" and then the guy doing a response said okay and made his video.

I think this fully highlights the point about how dehumanizing language from people with power in society is never equivalent. I'm not saying it's not rude or it won't hurt someone's feelings but the fact that a man can shrug and go on with his day vs. actually threats of implied violence that often undertone the other shows why these two things are different.
