Why not? You can simply say that sexism is harmful to everyone and that regardless of gender, our interests are the same on this. I don’t think most will have and issue with that and if they do, it can start a useful discussion. That being said, I have a bit of problem with an overly focus on women rights over general human rights, but I do understand the connection and can talk about both in both spaces.

If they could, they would. Laws aren’t passed because it makes sense, but because they benefit the rich.
