I’m on the progressive left. At best, it’s treated as a social nicety that we ought to offer each other, because it’s perfectly reasonable to expect functioning adults in a society to be polite. It’s hardly a meat and bone issue for me, and I think you’ll also find that to be true for actual progressive left politicians like Bernie and AOC. Much of the progressive left, despite what Fox or OAN is telling you, is focused on actually fixing economic issues that impact everyone, like the outrageous cost of healthcare.
