Let's assume that all the issues are binary (i.e. you are either for or against a proposition). But there are a large number of them. Humans are lazy. We try to use few categories to organize people we come into contact with (e.g. left or right, colored or white).

What will happen next? We feel that "the other side" seems to be all around, almost half the population. Example: many who oppose abortion probably also believe Black Lives Matter.
