Considering the stakes, I think it is more intelligent to be cautious and to try to make use of some of the lessons of the past than to be in denial.
Not saying I agree with Trump; I'm simply playing Devil's Advocate.
A guy who wants to ban people of a whole religion to enter his country, who calls all Mexicans rapists, a guy who publicly promotes bullying and discrimination, a guy who feels he has to defend the size of his penis, a guy who lacks any kind of manners, any empathy, and any cultural sensitivity, is a terrible person to be the president of the a very powerful and influental country. And a terrible person in general.
The public figure trump is, by all measures of the civilized, modern world, a terrible person. And the only three groups who would support him are: 1) terrible persons themselves 2) stupid 3) desperate.
And 3) is the most likely option. This vice documentary shows the desperation of Trump supporters quite well. Or rather, the hope they put into Trump as a result of their frustration and desperation due to the seemingly never-ending struggle they are facing. https://www.youtube.com/watch?v=ezvBs9SYxIY
