I use to have a friend like that. He was't that bad but still annoying. He worships 'Sinfield' and 'Curb Your Enthusiasm' but when he told us about it, and me and another one of my friends said we did't care for it, he when ballistic and told us the shows and music we watch and listen to was shit. Everyday without fault he would ask the metaly challenged kid 'Why are you so retarded?'.
I don't think he ever said anything about politics and religion but if he did it would have been like you said.
Luckily he dos't go to my school anymore so yeah, I'm cool.
