It is not that his supporters are "are all evil, ignorant rednecks" its that his polices are immoral (more torture of "terrorists" for example), anti-american (ban on Muslims or tightening libel laws) and anti-freedom (restricting trade, highly selective of press, stop and frisk).

He is not just a terrible person, he is a grave threat to the republic, IF he does what he said he would do. If he does not he could be a good president, but at the moment I can only assume he means to do what was said and that is a moral and constitutional disaster.
