I have a family member that went full transition female to male. They are way happier now as a straight male than a gay woman. It took me a long time to look at them and not see who they used to be, but I get it now, this is actually who they were all along and are way better off now than they were before. It may have even saved their life. They were born in the late 70s, this isn't some kid raised by the internet, its someone that had the same 80s/90s analog upbringing as many of us here. They didn't have to be taught to think or feel this way, it's just how it was and I believe them
That being said, nobody actually identifies as a cat, outside of Maureen Ponderosa or a few pronoun-bedazzled Tik-Tokers that crave to be unique and different from all the other unique and different Tik-Tokers. Transitioning isn't going away but Xim/Xer's and the pronoun laden cat people are a fad that will be pretty cringey in retrospect. It's like people who used to say they 1000 year old were vampires on my space. Where are they now? 2 kids and a white collar job. They grew up and got on with their lives.
