I get the sentiment, and by no means are the reservations good or something that should've been how it played out, but I do feel like putting them on the same level as ICE centers and concentration camps downplays just how bad those latter two really are/were.
I get the feeling you've not been told about all the death and disease Native Americans experienced in reservations, especially at the beginning. The only real difference is reservations did not have buildings...they were just wastelands.
