that's ridiculous, most humans are natural centrists with very few people making up the extremes.

Posts such as this are sociologically amusing, "meta-heuristic" and the like. Using prepackaged terms to disparage people and dismiss them, without actually having to think objectively and consider opposing viewpoints. Also interesting how the choice of language completely outs people, as the extreme right/left adhere 100% to their respective terminologies, to signal membership and loyalty to their group. This post is a good example.
