OP has said that he's "exhaustingly obtuse" and that being so qualifies as a disability.
OP you need to understand that being "exhaustingly obtuse" must be 1) diagnosed by a qualified mental health professional (think psychiatrist), and 2) something you told your employer before you were fired. If both of these requirements haven't been met, then you don't have an ADA accommodation case. Period.
Esteemed Colleagues, knowing what I know about asbergers/autism in the workplace, I think we're not going to get anywhere with this OP. He is hanging on to an idea and won't let it go. Only a mental health professional can help him to understand his problem. We are not mental health professionals, ergo we cannot help him. I reco that we stop responding to him. Maybe after a while of silence, he will go elsewhere for help.
