You can complain all you want about two or three people being a "COD fan", but that's possibly half to the only number of kids there that are like that. The reason you seem to think that you're the only smart person in school is because of the combination of intolerance and ignorance.
This is called "Intolignorance". You know for a fact that there are idiots, and you can't stand them, but you're too dumb to differ everybody else from the few kids you can't stand.
So next time you want to complain about your school being full of idiots, stop to think about how many people are actually in your school, and how many people you think are stupid.
