You are of course right that most people aren't like this. This thread is about those few who are, and how they can end up dividing everyone else, unwillingly, into accolytes versus enemies. It's not safe to say "I am left/center/right/whatever but I don't think this is the way to go about it" around this type. It is a separate axis from left-right, and is maybe correlated with the authoritarian-libertarian axis.
