I think throwing around "internalized misogyny" is a bit reductive. Real life is complicated.
For example, I "followed tradition" but was perfectly aware it was a sexist tradition. I didn't go along with it because I was blind to it being a patriarchal tradition.
But it was not something I wanted to have a fight or create bad feeling about. To me, there were other issues in my marriage that were more important.
I needed to conserve my energy for those and eventually I was able to use that energy to do other more important things (e.g. break free from a shitty relationship, after having tried my utmost to make it work). Rocking the boat over what surname to use just wasn't high on the priority list.
Also my surname is one that gets misspelled, mispronounced, and sometimes mocked, especially in the UK. Why would I saddle my child with it? And personally I think double-barrelled names are pretentious (though if that's what someone else wants to do, fine.)
So it's a lot more complicated than pointing the finger and chortling over someone else's "internalized misogyny." I also shave my legs once every 3 months or so. I'm perfectly happy to admit that that's sexist too but I do it anyway because I don't live in some idealogically pure feminist world, I live in the real world, and I consider other things I do to have far more feminist impact than this issue.
