> Is there a fair way of denigrating Trump supporters?

Yes, by realizing that he won because of his economics, not his social positions. The rust belt votes of economic issues, which allowed him to win. The poor in the area lean to whoever will help them not be poor, or at least say they'll try. Clinton embodied the status quo, Trump was change. They might not have liked him, and in fact a sizable majority do not, but realizing it was a pick of the lesser of two equals hopefully restores some sympathy for the other side, which is sorely needed today.
