Is talking to your friends publicly stating anything?
This woman obviously wasn't because she received immediate pushback from other people there. They're in a baby group, not friends.
And honestly, I've read plenty of AIBUs about men making sexual comments about other women (and how fuckable they are) or about how they don't like fat women or whatever that were considered rude because they made the woman there feel uncomfortable. Privacy never seems to be a defense for men's behavior.
You are suggesting that womens private conversations are somehow leading to mass hurt of people who aren't there to hear them, and that women should not make any reference to their sexual preferences in order not to contribute to societal tropes.
Okay, firstly I very explicitly didn't say this.
Secondly, you keep harping on about privacy but I'm not sure why. Probably 50% of conversations on mumsnet are about the private conversations between an OP and her DP/DH. These conversations are often classified as misogynistic or contributing to misogyny even though they are "private". If you don't think that the personal can be political or that structural inequality can work itself out in private gatherings, then how can you even believe in feminism? It's literally the heart of feminism.
The thing about "people not being there to hear them" -
. So you'd say this stuff if a black person isn't there but not if they are there? In fact, that's interesting. Why not? Why wouldn't you say to a black person's face that you don't find them attractive at all? Why wouldn't you say all of this in front of black people? Explain in exhaustive detail how you would never date them.
Because I bet all the people talking a really big talk on this thread have never done that.
