The logical end state of this belief is a civil war. I assume that in lieu of trying to change minds you're buying guns and ammo and trying to organize like minded people into a militia to protect your safety? Cause if not, I don't really think you really believe that a significant fraction of the country wants people like you dead.
Not sure which hated demographic you fall in, but I have friends that are suddenly being threatened by individuals who now feel free to expose their true selves. I can't believe almost half the population are like that though. Escape may be the best option for a lot of people at this point. My friend doesn't realistically have that option due to finances and skillset. I do think people who aren't in immediate danger can pull a lot of people supporting those fueled by hate away from their positions with calm dialogue.
In my experience as a chronic immigrant, most people are nice but there are some a-holes who would want to harm you or see you get harmed but they would not act unless they feel in power.
Therefore, most of the time you can just ignore them and your experience wouldn't any different than the natives who would also encounter a-holes for different reasons. The problem starts when someone in power to affect your life is one of those but in normal times you still can push back by questioning their actions as they still seek approval from the larger society.
The case with Trump seems to be the same with the case with Brexit: Those a-holes(not everyone who support those but a subset of them who are a-holes) start believing that they are in power and the society approves them therefore they can act on their instincts or plans.
I was working in London on the Brexit referendum day, some of our Spanish developers had trouble with people from their neighborhood right after the referandum.
