I take your broader point, but I don't think it's 50/50 as much as it is a vocal 10% on either side with the majority remaining pretty moderate and reasonable. I don't personally cross the divide, I'm a political liberal (earning me the 'socialist' brand from the right) but I don't dabble in the tribalism and try to be charitable toward those I disagree with (thus I'm a nazi to the 10% on the far left) but there's still a huge swath of people in the middle.
