1. The US-Mexico border wall. The purpose of the wall is to prevent people from illegally crossing the border to enter the US. Say what you will about its effectiveness. I doubt it would be that effective and think our money is better spent elsewhere. But if you support it, you'll be branded a racist.

2. Deporting illegal aliens. If you agree that people who are in the US illegally should be deported, you'll be branded a racist. Race has nothing to do with it. It's the legality of it. If you don't like the law, lobby for it to be changed. You'll also be accused of hating all immigrants (i.e., ones here legally) which has no basis.
