Can’t speak for parent, but when I describe the immigration jails as “concentration camps” I do have a political motive. There was a political motive in calling them “immigration facilities” in the first place. I simply want to call them for what I believe they are. When describing the nazi camps I say “death camps”, as to not conflate the infinitely worse horror of the nazi camps.

There is usually a political motive behind what controversial things are called. There was an active push from the oil lobby swap out the terms for the climate disaster from “global warming” to the more innocent sounding “climate change”. Then recently some media companies made the political decision to start using the term “climate disaster” or “climate crisis”.

> working for XCompany is actual slavery

I don’t think this is equivalent (even though it sounds like it to your ears). The ICE facilities can accurately be described as concentration camps. The victims are kept against their will—i.e. imprisoned—in camps in dedicated camps. This is an accurate term. Slavery only applies when you are forced to work for little or no salary. I.e. I often use the word actual slavery when referring to prison labor. This is a political decision on my part. And you are free to criticize this choice of word. And you would be right to say it diminishes the term when compared to the horrible cattle slavery in the Americas until the 19th century. But it is still an accurate term.
