I'd imagine he's capable of two facial expressions. Sneering and a grimace. His entire being is such an embodiment of negativity I'm not sure if I'm ever seen him make a post that didn't have negative intent towards something or someone. His initial presence on the board was a very unpopular one, dismissed as a troll and expected to go away sometime soon.
Yeah you don't know him at all, obviously. He's argumentative when it comes to politics but he's pretty normal on everything else. I've talked to him on AIM several occasions and it's been cool and relaxed, not awkward at all. He recently made a top 25 games list where he talked sweet about some of his favorite games. He's interested in the stock market and has taken some entry level economics courses and talks about that sometimes. Recently he's been disillusioned with the Republican party establishment and Fox News because hes watched as they've marginalized his preferred presidential candidate.
It's weird that you're putting him on an influential list when you clearly don't know anything about him.
