Asking her to take notes (as in, not asking anyone else), though, is a completely different story. However, I believe that some women handle it in a not very effective way. I might be a sexist too! If you tell me in a nice way (simply saying that you think what is going on is wrong/unfair) I will reflect, and most likely change my behaviour in the future. However, if you attack me, or even worse, say nothing but rant on the internet, I will take it personally, as an attack on my identity, and I might refuse to change, out of principle.
What we're trying to do here is enlighten a certain aspect of our society that is wrong/unjust, and I believe that should be done by teaching people, not attacking them.
(I'm not saying that the OP definitely took the wrong path. She might have told her boss, and they did nothing different, they didn't learn. In that case, I see no better option but to attack, shame them...)
