I think that I can boil it down to a simple thing: you hate people. People ruin everything that you like, whether it's hockey, music, art or movies. Does that about sum it up?
I say that tongue in cheek because I'm right there with you on some of it. I don't like concerts, either. Actually, I've never been to one because just the idea of them is such a turn off for me. I've been to several hockey games, but I don't like that experience, either. I'm also not a huge fan of seeing movies in theaters because other people take away from my concentration and I feel trapped (not in a claustrophobic kind of way, but "I'd like to get up to get a drink, but I'd hate to bother the other people in my row, so I'll just not" kind of way). I prefer to enjoy all of those things at home, where I'm comfortable, can pause at any time and others aren't bothering me. So, yeah, I hate people, too.
