I say more of a “Solidarity” like movement which encompasses the entire political spectrum. There are a lot of true liberals (not the fascists who call themselves liberals) who are truly appalled by this.
True..one of the things that will be necessary for a new party to flourish is it needs to champion populist common ground that has appeal to disaffected democrats, honest liberals, and small-L libertarians as well as conservative Trump supporters.
Threading the needle will be difficult for some won’t want to see the emphasis on their personal issues diluted, but a good strategy and prudential solutions that align with the American populism may ultimately see the same result, just via different means.
