Centrist “both sides” is the most milquetoast, bad faith shit possible.

Leftist “both sides” is about how at the end of the day, politicians want to look strong for being re-elected. And they is often keeping themselves and their cronies in power by any means necessary. From rigging elections and primaries, to underfunding government programs that enable higher levels of thinking, to even international assassinations.

It’s because most people don’t like right wingers, and they know it, so they try to hide behind that.
