It's not that the labels are charged, it's that they are nonsensical unless you look at them from a very narrow bespoke perspective, where "things I like" go on one side and "bad things" go on the other. Objectively (or even from any other biased perspective), it's rubbish.
(For clarity: I didn't "flip" them, I'm saying that they are both Communitarian and neither is a Classical Liberal.)
Typically, one would refer to the political compass as a good starting reference. It has two axes, left/right and authoritarian/libertarian. Communism is authoritarian left. DSA is more left, with some libertarian and some authoritarian. It's more regions than binary flags.
We are are talking about the famous Xi Jinping, right? The one that rules China with an iron fist? And not just some guy you know who happens to share the same name?
Accordingly, your insistence on drawing an equivalence between Bernie Sanders and Xi Jinping reads as very bizarre and out of the blue since Xi is Communist (Auth-left) and Bernie is left (mix of auth and libertarian but left on the orthogonal axis to authortarian/classical liberal).
If that doesn't clarify your mistaken read, then let us leave the conversation where it stands as I'm not terribly interested engaging in further platforming someone's personal flamewar topic.
I really think this says more about the biases of whoever came up with it (or their sources) than anything about reality.
