That some people are so easily subjected to propaganda that they without any type of self-reflection become rude and hateful and somehow think that their arbitrary political bias entitles them to this behavior. You're basically the internet equivalent of a sports hooligan swinging at strangers because the badge on their shirt is different from your's. In fact, you're a little bit worse since I'm not even wearing a badge or rooting for a team but simply saying: "you know, this sports stuff is kind of dumb and you guys fighting each other makes it even dumber." You're THAT guy. Someone who'd run up to and grab a random stranger who is trying to remove himself from the stupidity, like: "WHAT TEAM ARE YOU ON?! ANSWER ME!!"

It's kind of sad. Hopefully some of what I've said lingers in what remains of your brain and will make you come to your senses once it's marinaded for a while.
