Lots of transphobic cis people are agender eggs who don't care about being misgendered because they can't be. If you teach them what being misgendered feels like, they might decide it didn't feel bad for them, so it must not feel bad for out trans people either. That's teaching the wrong lesson.

I understand. Please don't do that for the reasons I stated above. Purposely misgendering transphobes only encourages them to purposely misgender us.
