I have tried to rationally discuss issues with many a Trumper. It never goes well.
I have come to the conclusion that it is best to limit your discussions with Trumpers to short interrogatives. Don't expect them to go very far. You really need to show the same sort of crazy inclinations to get them really going. I refuse to offer them this sort of support. Certainly I could shine them on, but then you become part of the whole "people are saying" feedback loop.
Its best to observe groups of them from a distance both online and in person. Only then do you really see what they are like. They
suck.
No election in the near future is going to depend on changing their minds - thankfully. Whatever happens in the short term is going to be based on trends in the country that are already well advanced versus how well the Republicans can stave off the numbers. Well, that and the votes of a very small percentage of the population that actually are swing voters.
