@joshsusser @FediTips To address your last comment first: I replied to this chain, rather than separately posting a reply, for this exact reason. If you have information counter to mine, I wanted you to know that your suggestion was opposed so that you could have the chance to go, "Wait, no, that's not right." I happen to hate when people try to argue against me in a way that's exclusionary and I don't like doing it to other people when I can avoid it.
It is clear that we have had two very, very different experiences when dealing with people using the tag. It may be worth exploring alternatives to it altogether (for example, using your own explanation for its purpose, something like AutisticPoster or AutisticSpeaker) since - at least to me - it is clear that it has been poisoned to some level by people using it as a gatekeeping device. I AM glad that you have NOT had that experience yourself; it is absolutely horrible and demoralizing to be shunned by what is supposed to be your own community because you present differently than whatever the expectation of the moment is and I hope that you never have to deal with that sort of behavior. And if you have elsewhere, I am sorry you have - at the end of the day, regardless of tags or disagreements, we're autistic and our voices should be heard and respected regardless.
