I’ll say it again, not racist, just stupid.
“Concentration camp, internment centre for
political prisoners and members of national or minority groups who are confined for reasons of state security, exploitation, or
punishment, usually by executive decree or military order. Persons are placed in such camps often on the basis of identification with a particular ethnic or political group rather than as individuals and without benefit either of indictment or fair
trial.”
AOC was correct. All of it is terrible and it sets a bad example on the world stage.
