I have to listen to a lot of casual sexism and misogynistic crap at work.
When I do get fed up and speak out I have generally bottled it up for a bit as I can't always articulate what I'm trying to say well (too nervous).
I fizz quietly to myself, feeling too intimidated to tell them to STFU!
I actually did point out how bad a particular conversation was the other day, it was brought up as a bit of a joke later as in "you'd better not say that in front of Leonard".
All I said was along the lines of "there's no way you'd be saying that if it was about a man", I guess they didn't really have an answer.
Any tips on being articulate and not crazy sounding?
