It's easy to underestimate how deeply polarized the US really is.

Trump in particular is so far out of the bounds of normal politics that to many people, support for Trump appears no different than support for, say, Mussolini. It may only be fringe extremists playing the racial supremacy song, but half the country is marching along to the beat. At that point it doesn't matter what your private reasons for supporting a Mussolini or Franco or Trump are - you're still a collaborator. The justification for boycotts etc comes from that point of view.

It's a difficult problem - the left (such as it is) needs to find some kind of productive path forward, but I'm not convinced that pandering to the sensitivities of people who have no intention to reciprocate is at all useful.
