One of my least favorite political tropes is the claim that "America has two left-wing parties" or "America has two right-wing parties" or "both major parties are socialist" or however else you want frame this. The argument goes that even the Democrats aren't truly left (or even the Republicans aren't truly right), and so one side of the political spectrum completely controls discourse.

Taken as an absolute claim, it's meaningless. Both US parties are on the same side of center? What center? By the standards of the Soviet Union, both US political parties are extremely far right; by the standards of Pharaonic Egypt, they're incomprehensibly far left. Whose standards for center are you using? The objective standard? Are you sure that exists? Are you sure you're not just taking your own personal beliefs about what seems reasonable, declaring the middle of that the objectively correct center, and then getting angry when the real Overton Window isn't centered around that point? People act as if you should just be able to take the leftmost thing imaginable, the rightmost thing imaginable, draw a line between them, find the middle, and then get angry if both US parties are on the same side of that line. But maybe they have poor imaginations. The leftmost thing I can imagine is an insectoid hive-mind; the rightmost thing I can imagine is a rapidly expanding cloud of profit-maximizing nanobots. Are we sure that a line drawn exactly midway between those two things lands on Joe Biden? What if it lands on anarcho-capitalism? Does that mean every existing human is left-wing?
