I prefer “trans-disparaging” personally.
I have an issue with the idea that somebody who opposes the Trans activists are the ones who are trans phobic. They are standing up to their face and debating them. Seems that they are willing to oppose the trans movement. People like AOC are the ones that are actually afraid to disagree with them, afraid of the conflict and bad press, making them the literal definition of Trans phobic.
There’s no such thing as a “Trans Person”, so you can’t be phobic of something that doesn’t exist.
I’d rather have X-Ray vision or superhuman strength, but super-transphobic isn’t a bad super-power either.
