There is a conversation around the practice of women taking men's names on marriage, of course.
It's an interesting topic and a complicated one, when you cross it back to societal expectations, norms, upbrining, family expectations etc and so on.
The options that exist dont' contain an obviously best one either. The general options seem to be keep names and kids get men's name, double barelling (won't work as more and more people double barrell they'll get longer and longer!), making a new one up which is a nice idea but not that popular yet and does disconnect from everyone in the past, man takes woman's name (have known this happen). Otehr option - the couple keeps their own names and the kids have the woman's name, people will assume he is not their father. That's just the way it is, in our society. I think some people wouldn't be bothered with doing something they know will make most other people they meet draw the wrong conclusions!
There's no brilliant or easy answer, which is why it's always being talked about.
Anyway there are lots of conversations, this man wasn't having one though, he was being a grade A dick. What kind of a man digs into a woman's personal and home life choices (at work), finds something that allows him to say "HA! You're a shit feminist! You're not e feminist at all no matter what you claim! I'm more of a feminist than you!!". Now I hate this word but in this case it fits, he was being a nasty little bitch.
Also, men hate it when you call them bitches, undermines their ideas about gender and insults, although obviosuly the root is misogynistic it can be worth it to see the look on their faces. Only women are supposed to be "bitches" they really don't like being called on it
I once called my dad a slut, he did not like that, his face was a picture of utter shock.
