My bet is IRL he's just a pasty, sheepish nerd who rarely expresses any kind of genuinely controversial opinion to someone's face
None of those things disqualify someone from sociopathy, the term itself isn't an insult, it just means you got raised in an environment that warped your sense of empathy in a permanent way. I'm not trying to play psychiatrist, but I do think he has more serious underlying problems than it would appear. Some mental illnesses are progressive (lol), so it's possible he's simply getting worse. I didn't know him before gamergate so maybe he used to be semi normal, but he's become a monster, even if he's too lazy to do anything monstrous besides imply that downies and children and senile folks are evil.
I don't think anyone really enjoys dumb people and I think we can all agree that genetically engineering diseases away is a good thing, but Bob is not saying these things. He is saying much worse consistently and he's an adult and he's serious.
The real danger of people like Bob isn't that he inspires hate in his followers. It's that he is stoking the fires of hate in his political enemies, some of whom would happily hunt him and those like him down and leave them charred and hanging from a tree, if only they had the chance and a strong enough rope.
I don't know if you all are aware of it but even 8/pol/ is banning anon for being "too bloodthirsty" right now. Outbreaks of political violence are becoming daily occurances in the US. Bob is not a threat to anyone, but he is a shining example of the type who needs to shut up before he's shut up. People like him and Wesley/Larurelai Bailey seem to have no real awareness of how close we are to everything falling apart. Trump supporters will not let Trump lose. The CIA and deep state will not let Trump win. We're at the point where political commentators are cheering on an unelected shadow government that until recently was considered a conspiracy theory. If we manage to avoid civil war here, we will be very, very, very lucky. Bob and his ilk are only making it worse. I really have no pity for him anymore.
If he's not crazy, he's so stupid it might as well be a form of crazy.
