I don't agree that Damore has "openly sympathized" with white supremacist groups. Unless you consider admitting "Grand Wizard" is a pretty cool title to be... "sympathizing". (It's a pretty cool title. Reprehensible humans have that title, but it's a cool title.) The fact that he didn't anticipate how badly this post would be received by the public though... a clear symptom of his presence on the spectrum.

As a fellow member of the spectrum, I can fully see where Damore fits on it. In some ways I agree with his actual points (not what the media has claimed they are), but his presentation was poor, and insensitive to how it would be received. And a good chunk of his memo was just... not good. He never intended it to be public, and it certainly wasn't fit to be (I believe he considered it a work in progress, and was looking for constructive feedback), but someone angry at him decided to make him a public figure overnight by leaking it and ruined his career.

He obviously made some very poor choices on who to associate with afterwards, not realizing the political implications that came with them. He failed to see how free publicity provided by certain parties would associate him with them.
