I think there's an incompatibility between "they're in practiced used all the time" and the fact that no two people can agree on where they are. I think there's a perception that there's a settled position for Right and Left, and that it's politically useful to speak as though there is, but when you start poking at where those endpoints actually lie the whole thing falls apart.
