I think this could be a story for Steve. This isn't so much a defense of Trump and Trumpsters as it is a comment on partisan rhetoric. Democrats call everyone not in their tribe a racist and have in some ways stripped the word of real meaning. There's a lot of mind reading, word twisting going on. A desire to see the government enforce immigration law need not be racist.

I don't know if you've done much international travel but outside of the EU, immigration laws, especially pertaining to work are strictly enforced. One of the big changes in the US pertains to immigrants reporting their whereabouts. When my wife immigrated to the US in 1970, green card aliens reported their address on one form every January. Every time they moved the reported that on a different form. She did that until the became a naturalized citizen. Nobody gave a thought to immigration control being racist, it was what every country did and most still do.

Passports now have chips with your data and picture and upon entry into other countries it gets compared (facial recognition) with a camera at the immigration point. My last trip to China they even had it in the hotel that I told immigration I was staying in. Going into the Dominican Republic my daughter mentioned to me that I and the other man in our party who was wearing a hat were told to remove our hats. I pointed to the camera; they were doing facial recognition against our passports.

The point of my comment is that people resent the hell out of being called racists because they are to the political right of Karl Marx. It does not lead to productive discourse on racism.
