I can honestly say I've had no hostility. In the early days I said, "I prefer Ms, if that's ok" And it was not a problem. There was the occasional "joke" but nothing offensive. I was never aggressive about that and the kids I taught called me Miss or Mrs and I wasn't snarky enough to correct them, they were only little.
I took my husbands name because I didn't have the courage in the early 70s to keep my own. He wasn't fussed either way. A few years later, I'd have kept it.
I'm quite a laid back feminist in many ways but get very annoyed about certain causes. I was born a woman, I have no penis and the correct hormones for my birth state. That makes me a woman. When I wear trousers, which I nearly always do, I don't feel like a bloke. Neither do I identify as one.
I believe in a woman's right to choose and men need to stay out of the argument. No uterus? Not your business.
I raised money for women's refuges when they were just an idea. I still support them and there is no place for penises in them, unless on children.
My elder son told his teacher I was a radical feminist and he was pleasantly surprised to find I'm quite sociable.
I am pretty radical about certain causes but I always try to argue nicely because that seems to work better.
Not always though. I have been known, when infuriated by misogyny, to lose my cool loudly. DH has been known to turn into a cringing Basil Fawlty when my hackles start rising.
Sorry for the essay.
