I feel there is some over thinking here by some in terms of the ethics. People with autism are not going to have their treatment by other people significantly affected by the Hitler's genetics indicating that he could possibly have autism. As noted in the article the idea was not a nes one. And while i am accepting of the idea that you don't need to be mad to be Hitler, I think it might help.
I understand the desire to normalise mental heath issues but I think some of the stuff in the article risks proper support of such issues if they are seen as just effectively personality.
