You do realize your entire explanation was extremely sexist, right?
For one thing, if I say f*ck that doesn't mean I'm not a nice person and that (a) men are going to try to beat me up and (b) if they do it's my own fault for saying f*ck...
For me it is not about expecting to be beaten for a "wrong" word. When I was younger, I disliked hearing such words from people I liked. Now I can be OK with them, even though I don't use them in my speech. It seems I need only one word which is almost "мат", but not as rude as the other words which are called "мат" in Russian.
Russians also teach young people to give up the seat in transport to elderly people, to handicapped people, to passengers with kids or to pregnant women. This is not ageism for us. Some even are used to give up the seat to any woman. Others think that this is sexism.
I don't say this culture is right or always better than other cultures. I just say it exists.
It is said that ***19 is more dangerous for elderly people, right? I don't think this is ageism.
Sometimes people think that biological difference matters, sometimes they don't think so.
