The problem with this argument is that you imply that the left could simply choose to do away with what you call progressivism at no cost. In fact, what you’re calling progressivism and what is rejected by many Trump voters our fundamental rights for women, gay people, other minorities, et cetera. The US is not particularly progressive by the standards of most developed democracies. It’s true the other countries have managed to maintain abroad consensus around minority rights in a way the US has not, but it’s inconceivable to concede much of this ground now. Gay marriage, reproductive rights et cetera. Are not simple things to give up. I find it almost impossible to seriously entertain arguments against them. What you’re asking for is for educated people to fundamentally undermine core principles that are part of a fairly coherent and consistent world view.
