- People had a choice between two evils, and practically no way to elect anything else. Democrats rapidly deteriorated the quality of life of Americans and funded cruel genocidal wars, which led many to protest vote Republican.
- After Trump actually won for the second term, many regrets were voiced about this protest vote. Ultimately, this led to what we have now: complete domination of Democrats in Congress. People really, really despise what's happening, but can't do much else until the next presidential election turn.
- Trump won his first presidency through representative vote; popular vote (i.e. votes of the actual voters) was on the side of Hillary Clinton. Basically, in every actual democracy Hillary would win that election, but the quirks of US electoral system decided otherwise.
So, in aggregate, Trump won his first presidency against the will of the people, and his second one in large part due to protest vote against war and genocide. Protest vote backfired, and people try to at least recover some of the damage while thinking of new ways to make at least one party give a single damn about what population wants.
Besides, this fails to mention that people are different, and lumping them over their citizenship is extremely counterproductive. If anything, it serves the rest to feel superior while doing nothing. At any given time, about half of US population wants global cooperation, social reforms, and common good. They are not your enemies in any way, shape or form - they're only unfortunate to be there in this day and age.
Same goes for other corners of the world, be it Russia, Israel, Iran, China, or anything else. Everywhere, there's plenty of people who fight back, who do not agree with whatever their government is doing. They are not your enemies. In fact, these are often the very people you interact with, and shoving blame in their face is hypocritical, counterproductive, and plain rude.
