Note however that one way to make a society appear to be less politically polarized is to silence the voice of groups who are not being served well by the current political status quo. When voices fighting for representation and fairness and equality are amplified, and supporters of the status quo resist (which they nearly always do), that will necessarily increase the apparent polarization, but I don't think that's a bad thing, and I certainly don't think it's worse than those voices remaining silenced.
