I concede there are many things said here that wouldn't be allowed elsewhere. I don't think it's usually borne from hatred or fear though. A lot of times they're things people don't want to hear and they get shut down by labels like transphobia or racism, but it doesn't mean it shouldn't be discussed. Aimee Challenor is a good example of that. Criticizing her was considered transphobic and a banable offense on Reddit.
