ICE is a racist and corrupt organization that oversees nightmarish modern-day concentration camps. For the most part, people who sign up to work for ICE are doing so because they specifically want to be in the position of punishing vulnerable foreigners who haven't done anything wrong.
How should I go about telling ICE that they can fuck all the way off up their own asses? Who should I notify that I'm calling them a division of the MAGAstappo? Do I need forms in triplicate stating that it is my firm opinion that not a single person who works for or cooperates with ICE is or can possibly be a good person? Do I specifically need to use social media to say that nobody who works for ICE is deserving of love?
Report them to themselves for human trafficking? Better yet, report a local racist.
Caveat: providing false information to law enforcement is a crime, unlike law enforcement lying to other citizens. In all seriousness, just avoiding them and not aiding them goes a long way, too.
