@NightOwl it's not that.

People who are sane and this hateful at his age spend their time doing stuff like propping up right wing think tanks, writing memoirs about how great Kissinger is, or introducing discriminative policies into their HOA.

Spending their time and energy serially harassing hot dog vendors and people's dogs, on the other hand, is more the pastime of those with mental health issues.

Also, I saw the first video, he had a manner that strongly reminded me of paranoid delusional people.
