N.B. misandry is not real because men are not systemically oppressed (uninternalize your reddit MRA today: men suffer some drawbacks under the patriarchy but ultimately still maintain it due to the large amount of privileges they receive under it!)
probably your immediate reaction to defend yourself and your gender. If you hadn't been trained, your knee jerk reaction would be to look for ways to accept a viewpoint like that, rather than to poke a hole in it. I know it sounds serious and scoldy, but just let it sit with you for a while.
Perhaps I'm projecting, but I noticed it was something I was guilty of at times.
