This isn’t unique to the US. The US did not invent the concept of a midpoint.
What other countries have a two party democracy? And what other countries smear the other parties to the degree of US politics?
I get you have an axe to grind, but I said I was an outsider, how am I supposed to know one side is right and one side is wrong? If one is right and one is wrong, that really only makes one party now doesn’t it? You seem to want to point out math to others, but have an issue understanding it yourself.
