Words have definitions and meanings, but those often vary with context. In some contexts, "bad" actually means "good", for example.
For two generations, "concentration camp" has been used to connote certain meanings which do not apply to these detention centers. If your goal is to avoid those connotations, then you should choose a different term for these detention centers.
My theory is that the goal is actually to have exactly those connotations, even though they don't actually apply in this case. This theory is based in part on your efforts to push a false equivalence between America 2019 and Germany 1936.
This is entirely uncalled-for.
I say they're not concentration camps, because that term has strong connotations in our culture, that don't actually apply here. Calling them such is effectively the same "I'm not saying, I'm just saying" dishonesty behind the CT practice of JAQ-ing off.
