One thing that really bugs me is people thinking they have any sort of cure for it. THERE IS NO FREAKING CURE. Maybe in the future. But not now.
Worse though is anyone trying to push that cure onto others. I'm not going to drop any names here, but... on a certain other autism forum, there's a certain individual that pretty much goes on about this non-stop. He's sure he "cured" himself, and keeps endlessly trying to push his method (which involves a certain diet and habits) onto basically everyone. This is someone who was NOT diagnosed professionally but instead self-diagnosed, which makes this even more dubious. When warned that his "cure" might not only NOT work for everyone, but could actually lead to unexpected harmful effects (everyone is different after all, some might have very negative reactions to something like what he proposes), his response basically boils down to "NO U" except in 10000 words, and he just keeps going forward. Anyone here who has been to that forum probably knows exactly who I'm talking about.
