Haha, I think everyone here is quite convinced that Double Dragon is deeply autistic. That, on its own, would be fine. You can live with most forms of autism, and while it's certainly a handicap, in most cases it doesn't have to be more than a mild annoyance. As I have expressed many times on both RationalWiki and here, I don't mind dealing with a fellow editors "peculiarities" − autistic or otherwise.
The problem with DragonDragon however is that he's not just autistic, but that he seems to be completely unable or unwilling to perform any sort of reflection of his own behaviour, resulting in a "I can do no wrong"-attitude and ever-escalating conflicts until the other side backs down or gives up, or until he gets kicked out. For example he never really understood why his RationalWiki antics were problematic.
This is true for even the most minor things like episode numbers, capitalisation, minor translation issues, etc. He *has* to have *his* way.
In other words, he's an asshole. Yeah, an autistic asshole, but the reason there's a thread here for him is because he's an asshole, not because he's autistic.
