that's just edgy humor that's everywhere on the internet. gender identity is a really easy target to make retarded jokes for small brains
anyway something happened to me kind of recently, pre-covid though. I had a friend come out as trans that I was friends with for a long while a few years ago. it started off fine, I really dont care what you identify as ill just say what you want me to call you yknow. their entire personality shifted though, they got hyper sexual and so awkward to even start a conversation with. I put up with it, didnt talk to them as much whatever. stopped talking for a good while until they eventually came back around to say whats up. kinda rebuilt the friendship until one day on their public twitter they started posting videos of them jacking off wearing a diaper. if they had it on an onlyfans or something where I couldn't see it i'd probably be alright, but since I was subject to that absolute nuke on my eyes I broke contact with them.
I personally dont want to be someone that associates with another person that pretends to be a baby, builds cribs and play areas in their room then records them shitting in their diaper for twitter. they took that as I hate trans people, kept their porn twitter private but then made their own personal venting twitter and tried to tell all of my closer friends that I was transphobic over it. whole thing was really stupid and easily explainable but they have me blocked on their twitter. they occasionally posted about me on their public one so im sure they're still venting about it to this day. obviously I don't have anything against trans people but if you want me to see your weird fetish or some shit maybe ask if I like people shitting in diapers first. last I heard from them they dropped out of college and had a twitter breakdown, started a just for fans page and had some discord grooming allegations - basically turned into one of those people that posts public porn, says that minors shouldnt follow them on twitter and doesn't really regulate anything beyond that while being heavy into age-play
it didnt really affect me mentally or anything, maybe at the time since I knew them for a few years but ultimately being a gmod roleplayer nothing really surprises anymore
