I'd love to know how many feminists have changed their name by seed poll to not have their parents name
Would you? I don't know why that would be helpful, but I'd suspect not many women object to sharing a family name or names with their parents and siblings. The whole point is that many feminists don't want to change their name from the one they were born and grew up with, because it's .... their name!
Claiming victim status because other women don't follow your choice to keep your name is bizarre
Nobody's 'claiming victim status', but if you mean 'thinking name changing on marriage is sexist and indicates we live in a sexist society', then that claim isn't made on the grounds that it's a problem that other women don't have an issue with it. This seems a bit confused.
Have you all made up surnames for your children? We wouldn't want Dad or Mum to be claiming ownership
You're not 'claiming ownership' when you give a new baby your surname. Babies have to have surnames. Of course, some people do come up with new ones, it's not that uncommon. The problem is rather that whatever name a baby is given, the girl ones are much more likely to change it to that of their spouse later than the boys.
