I genuinely think on some level they are upset that trans people are getting "attention".

This isn't all of them of course, and I notice it more with women than men, but they seem to be almost jealous in some way. Doubly so for TERFs. They think they're getting special attention.

A lot of them are just plain reactionary though and just not willing to learn anything new. Like those dumbass people who are like "uhhh, in school we learned that there were two genders lol" like you didn't also spend all of high school physics pretending that friction doesn't exist.
