There have been a lot of cases online of people identifying as such, then espousing transphobia from a position of "I was trans once so I know it's bad" which is not only really shitty, but opens up a whole big can of worms about "who's really trans" that can delve deep into talk of stolen valor, trans-medicalism, people who just transition socially vs those who undergo medical treatments, nonbinary people taking stray shots all over the place... It can be a bad place in trans discourse.
