I don’t think you are paying attention to the abject cruelty in the administration’s own discourse about these facilities. The U.S. president describing with barely restrained delight his anticipation that escapees from the new facility in Florida would be eaten by alligators. I suppose if called out on it, he’d claim it’s a joke. I’m sure many regimes in history had their own euphemistic terms for facilities such as this; but purposeful cruelty is a cardinal feature of concentration camps in my view.
