What's truly horrifying about Trump isn't Trump himself, but rather that an extremely alarming number of people support or at the very least condone racist, intolerant, xenophobic nationalism, and would like to make such radical, aggressive views the national policy of a superpower. It's the same kind of societal mentality that allowed a chap named Adolf to rise to power about 80 years ago.
Are politics in the US so robotically binary that Republicans would vote anyone to office as long as the candidate is nominally Republican? I really can't fathom how the "conservative" option, in the general sense of the word, is voting for a random rich loon who up-ended the conservative party, as opposed to an actual politician who at least has some experience in office. I'm sure Hillary has flaws and all, but voting in democracy often constitutes picking the lesser evil, and I really can't understand how said Trump could not be considered the greater evil. Are Americans taking democracy so lightly they'll vote any rich idiot with radical ideas just to spite the other party? Is their hubris such that they truly believe, in their heart, that "it [fascism] can't happen here"?
What's really ****ed up is that the aforementioned xenophobia and widespread intolerance doesn't trigger any alarms in the general population. Promises of making the lives of Muslim Americans hell? Literally walling off the southern border? Encouraging gung ho use of nuclear weapons? Oh, that's cool. It's comparatively inane stuff like the use of an email server or a mere dozen cases of sexual assault that can bring down a campaign to its knees at times.
I have to say that as a non-American, I've found this whole political race frankly baffling. Maybe Trump is too stupid to do anything drastic, but this kind of societal mentality really is the melting pot of tyrants, and unless changed, we may very well see the emergence of the next great dictator right there in the United States, in the near future.
