Based on what is upvoted here, I believe that this isn't a group of conservatives upvoting a defense to shit elsewhere. I view it as a modernization of Shermanposting
So to be clear, I believe the person is referring to the recent case of a German (white dude, electrical engineer iirc) who got picked up and treated so poorly during detention that he had to be hospitalized. The article I saw specifically mentioned the Immigration fuckwits encouraging him to get rid of his green card.
