TIL of the Horseshoe Theory. The idea is that the political spectrum isn't a line, it's more of a horseshoe shape. The extreme ends of the left and right are more similar to each other than moderate left and moderate right.
Centrists are also fans of the “horseshoe theory”, where “we want to kill black people” and “we want civil rights” are both the same thing. -- https://freethoughtblogs.com/pharyngula/2017/07/21/see-also-revelation-316/
