Or was this about race? About making sure everyone was clear that this is a country for whites?
If one persists in calling half of the country racist, one will surely miss learning the lesson here.
It's time to put the non-stop ad hominem attacks away and start making a cogent argument for your political philosophy. Yes, it's easier to just win the argument by default by calling someone you disagree with a racist and issuing ridicule, but you do not sharpen your rhetorical skill and intellectual curiosity that way. And one occasionally loses elections they probably should not have.
Trump also takes the Republican party further away from this ideal, much to the dislike of many of us Rs. But I'll do my best to keep the spirit of William F. Buckley style rational exchanges of honest disagreements alive best I can. This probably will include being a strong supporter of a primary challenge to Trump in 2020.
Bottom line is, you have honest fundamental disagreements with Rs. Don't call them racist and other names. Instead, grant them an assumption of sincerity, and make your case why they are merely mistaken, rather than irredeemably evil. That will have a better chance of persuading others.
