People don't have to be used in forced labor or be executed for it to be considered a concentration camp. It's the mass holding of civilians without due process, without intent to file charges. Which, by the way, is a violation of the Universal Declaration of Human Rights, of which the United States is a signer.
We keep being told that these people are all claiming asylum; which means that they have to be processed accordingly - tens of thousands of people. That processing takes time, and the sheer volume has overwhelmed any reasonable capacity. Again: what are we supposed to do with them?
We could call it an Internment Camp if that makes everyone feel better. But either way, it's a travesty.
How about "detention center"?
If they want to send them back, then send them back. Put them on a bus and send them back across the border. Or, if you want to try them for crimes, then put them on trial.
No way to know what to do with them until they've been processed, especially for asylum claimants.
Locking people up for months at a time in bad conditions and taking away their children is just inhumane.
The vast majority of minors are unaccompanied. Besides, if you don't want to be separated from your children, don't illegally cross the border into another country with your children.
