Living in SF I can emphasize with the frustration of not understanding why others vote (or see the world) like they do. At the same time, I literally laughed out loud at your last sentence because it just reinforces the reason some are voting like they are. You think insulting them like that is going to make them want to vote how you would like?
If polls are to be believed it looks like Trump is gaining with black and LatinX males. Funny seeing white people calling them deplorables.
Here's a potential option. Raise a bunch of money to send your fellow Democrats to a Dale Carnegie class. How To Win Friends And Influence People is still an incredible read to this day. And I'll tell what it doesn't recommend, going scorched earth in insulting people you want to be on your side.
