re: Let's all come clean, why is Trump so despised and hated by some Americans?

Have you interacted with someone famous in an off the record setting? Every single one of those politicians are every bit as coarse (if not worse) as Trump off camera. It's the same reason a lot of people respect Bobby Knight. Unlike the "polite" coaches, Knight had no "on camera" persona. Ask anyone that's spent time around Coach K, and you'll soon realise he was meaner than Knight ever was.
