For one he is a left wing extremists. He is a big fan of Obama, Biden, and Anderson Cooper.
He also name-checks Ellen Degeneres, but I'm not blaming her for it. To place politics on this is to miss the real issue. The plain fact is that the guy's delusional, he's on a vendetta, and he's very well trained. He could turn into another Eric Robert Rudolph.
Frankly, if I were to cross paths with him, I would be very leery of engaging.
