Immigration was a pretty big topic during the election. People knew what they were voting for. I find it sad that you find it hard to believe people have civic pride they want to defend.
Unless, of course, you're insinuating they do actually want that. In which case, your outlook of Trump voters is significantly lower than mine. Call me generous.
Now, of course, a lot of people saw this coming and have been warning about growing authoritarianism from Trump and his administration. But his administration is also built almost entirely on lies, so I can't be too critical of people who are confused.
