Trump's social autism is the source of his appeal. A Pew surveyfound that what Trump's supporters like most about him is his personality, not his policies. They like his personality more than his policies for the same reason that men like the sex scenes in pornography more than the plots: Vulgarity is the point.
Like many people, Trump is at his worst online. As of July, he had insulted 487 people, places, and things on Twitter. Technology, by separating us from the consequences of our actions, makes incivility easy. The internet is a rude place because it's a safe place. You can fight people without getting punched in the head. Online, the only things that get hurt are feelings and careers.
...Trump isn't solely to blame, but he's primarily to blame. He makes mean people meaner and dumb people dumber. The internet gives people a platform to be nasty. Trump gives them a template.
Putative Christian leader Jerry Falwell Jr. tweeted recently, "Conservatives & Christians need to stop electing 'nice guys'. They might make great Christian leaders but the US needs street fighters like @realDonaldTrump at every level of government b/c the liberal fascists Dems are playing for keeps & many Repub leaders are a bunch of wimps!"
Just as Jesus said.
...Lord Moulton, an English judge, noted that a nation's greatness is measured not by compliance with the law but by "obedience to the unenforceable," that is, by its manners. Manners are the tax we impose upon ourselves to get along with each other, to make life more bearable.
Trump is a reminder of how not to behave. To make America great again, ask yourself: What would Trump do? Then do the opposite.
