It only "promotes polarization" if you have already decided that anyone who uses it "dumbs down the level of discourse." If you instead give them the benefit of the doubt that they're trying to make an intelligent point about a situation or dynamic, and then try to understand that point, and then reason about that point's validity, then you will finally find yourself actually engaging in the "level of discourse" that you purport to (but are actually undermining with your kneejerk disdain).
