He obviously felt oppressed by all the straight people onboard and decided that the only way to stop feeling oppressed was to kill all who oppressed him. If you criticize him for this, you are obviously a homophobe. /s
As good a theory as any. So maybe he was jealous of the German pilot who flew his plane into a mountain?. Harder to do that with a train but if he overspeeds fast enough and long enough he’s bound to do some damage, which he did. So now I have to wonder if the guy is a queer muzzie? He looks to have enough face fuzz to qualify?
