The Trumpian worldview in full effect.
@pillsy W.C. Fields: "I'm free of prejudices. I hate all people equally."
That said, while I do think ICE is racist, I also think "treat all people in a vindictive and cruel manner" is kind of their MO. They're just even more terrible and inhumane to some. We tend to focus mostly on their treatment of Mexican immigrants, and for good reason, but they'll happily mess with anyone they don't like.
Back in 1999, when I was immigrating to the US, I had the fortune of getting two really nice customs officers (they do exist) and, while I was waiting for them to finish all my processing, the warning/misfortune of 1) watching other customs officers throw every single piece of clothing of a German on a work visa out of his suitcases every which way (some of them landing on the floor) because they weren't bright enough to understand his job description and took umbrage, and 2) talking to a very very nice man from the area (Boston) who'd been held for 24 hours after returning home from visiting relatives in Ireland because the immigration folks *literally did not believe a black man could have Irish relatives*. He was, of course, a US citizen. Which is probably the only reason they let him go after one day instead of longer. Such BS.
And they haven't exactly gotten kinder since 1999.
It worries me to think of what ICE may decide to do now that their worst elements are convinced (with reason) that the President is on their side.
