Exactly, Thinx.
I think there's at least some grass-roots rumbling because I might not have learned I was on this spectrum, otherwise. I believe some of us are here to write our own stories and then take them out into the world, so I DO actually see a value in "coming out" in certain places and circumstances. The misinformation out there is several yards deep (no thanks to Mr. Baron-Cohen...) and now that I'm aware of autistic traits, it's obvious we're everywhere.
And because I also happen to believe that neurodiversity shouldn't be considered a "disorder," because it deviates from the mythical norm, I try to watch which terms I use to describe those of us on the spectrum.
