A lot of these points confirm Progressive's bias that Trumpites are in some way morally deficient. However the one that struck me was this:
Lack of Exposure to Dissimilar Others
Intergroup contact refers to contact with members of groups that are outside one’s own, which has been experimentally shown to reduce prejudice. As such, it’s important to note that there is growing evidence that Trump’s white supporters have experienced significantly less contact with minorities than other Americans. For example, a 2016 study found that “…the racial and ethnic isolation of Whites at the zip-code level is one of the strongest predictors of Trump support.” This correlation persisted while controlling for dozens of other variables. In agreement with this finding, the same researchers found that support for Trump increased with the voters’ physical distance from the Mexican border.
Yep. As Twain said, “Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one's lifetime.”
