My impression is that most vocal progressives (even here in Europe) have stopped caring about the big picture in favour of domestic social justice. Killing a million people abroad = normal establishment politics, saying misogynist crap = unique threat to democracy. It boggles the mind.
Furthermore, the opinions that led to most of those were backed by a significant fraction of the experts in the relevant areas.
Trump, on the other hand, has some positions that are objectively wrong [1]. He has repeatedly claimed that global warming is a hoax and said that the planet is actually freezing. He said that doctors and vaccinations cause autism.
I find that a lot more disturbing and disqualifying.

Many progressives (Noam Chomsky et al) would consider the above actions corresponding to each president as rising to the level of war crimes. Hence, by this logic, anyone that voted for them is equally culpable. That's nonsense!
