I dunno, I don't think I'd go that far. SG's MC apparently has some legitimate trauma that fucked him up. Yes, that's technically EMOtional damage (insert Uncle Roger here), but I don't feel he's necessarily a douchebag as a result, he just isn't really connecting with people. Personally, I side with that MC every time he tries to dodge people that are looking to hug him. Me, personally? I'm a hugger, absolutely - but generally only people I know and actively like. There's a bunch of weird fucking strangers who keep trying to climb up on him, so telling them no and dodging them are perfectly rational decisions in my book.
