this is a genuine WWYD. I belong to a church. I'm very happy there, and enjoy working in the social justice group. But the leader is very nice, very liberal (as far as they can be while working with a traditional CofE group of people). I just know at some point they'll start talking about women as ciswomen.
I would object, and leave the group if my objection isn't acted on. But would that mean that I was being an arse, or just lucky (unlike those in paid employment where this crops up) to be able to do it?
