There's a massive overlap between furries and troons. Both disorders are caused by extreme coomerism, which in turn, based on my observations of these people online, seem to come from literal fucking autism.

Trannies, furries, pedos, scat fetishists, you name it - they're all people who are absolutely maddened by porn, they've jacked it so much they became insensitive to anything even vaguely normal, so they kept finding increasingly disturbing shit to jack off, and at the same time the kind of disgusting shit they jacked off became their entire identity. Again, autism.

I believe in this hypothesis especially because troons act exactly the same way as furries did about 10-15 years ago. It's uncanny. Any online community that doesn't bully them out will be overtaken and turned into a masturbatorium. It doesn't help that furries and troons are always severe autists so they basically live on the internet and they have more time to keep posting and get janny positions than normal people do. Really makes you think.
