For anyone having issues with the #ActuallyAutistic hashtag, there is also #AllAutistics and @allautistics (the latter being a recently created group that you can follow and post to).
They are intended for anyone who is (or thinks they might be) autistic (formally or self-diagnosed).
@FrightenedRat@ratcatcher@Gtmlosangeles@allautistics@actuallyautistic This is really tough.
The hashtag has to be short, hard to misunderstand and also should sound nice enough, so that people are willing to use it and it shouldn't make you seem weird for using it to others not familiar with the hashtag...
The best I could come um with is the seemingly most obvious #ImAutistic, but that could sound too much like a hashtag to come out as autistic and not to be used regularly.
[I wasn't trying to be controlling & suggest that there must be one and only one hashtag that everyone used, but I do think we need one tag with enough of a critical mass to let new members quickly locate a wide and diverse community.]
