I mean parties in the US are more akin to coalitions as you'd see in many European countries. I'm just saying that American parties have high variance within them. Sure, for your country Bernie/AOC may be centrists but in America they aren't. These are always relative terms that are context dependent. Sure, you can call the Democrats right wing but it's just not going to make much of a conversation because these are nationally agreed upon terms. (fwiw, I'm pretty sure I'm fair in assuming American context given the people I'm discussing)
