Chronically online people like to gatekeep things.
I'm on Tumblr and see all kinds of ridiculous bullshit gatekeeping, same for TikTok.
Yeah that's part of it as well, to be fair.
However, I do want to correct you a little bit on one point: as a person who struggles with Body Integrity Dysphoria (BID), simulating a disability does not always mean the person has a fetish for being disabled or for being seen as such. Some people with BID simulate the disability or disabilities that they need. For example, a person with a BID-based need/feeling of needing to be paraplegic may use a wheelchair; another person with it may feel a need to be mute, and may chose not to speak, and instead use sign language or a communication device (such as using a tablet to talk.)
I don't wish to start any arguments here, it's just a small little thing that bothered me enough to address it.
