Sadly have seen it myself. When talking to an ex-friend, they unloaded about trans people being sick delusional groomers. When I said that they would change their mind if they knew any transgender people, they responded that they did have a trans friend. I responded "then you should let them know what you really think of them and see if they're still your friend tomorrow." Hung up, blocked their number. I hope that trans friend is doing alright. Fuck transphobia.
