I guess I just can’t think of a better way to describe some of the stuff people say about trans people. It’s rooted in a deep hatred that warrants the suffix, IMO. I don’t think “disagreement” adequately describes the severity. ¯\_(ツ)_/¯
Like for example, if someone asks, "how can this person be a woman if they have a penis?"
These days, they'd get immediately accused of transphobia.
Shared amongst all these lines of thinking is an intense belief that the world would be a better place if the idea of being trans (and trans people in general) simply didn't exist, and that to move to that world, we should be detransitioned first, invisible second, and dead otherwise.
