This is all directly out of the Nazi playbook in the 30s. They didn't start out gassing Jews. They started locking up the mentally ill, disabled people, political opponents, "undesirables" like the LGBTQ community, outsiders like the Roma.
Murdering people was their final solution for what to do with all those prisoners. They started with concentration camps like the one they built in Florida.
They would never need the enormous ICE budget if they were only coming for illegal immigrants (and now homeless people).
Americans HAVE to get off their asses and stop this. Trump and his goons WILL expand the groups they're going after. This WILL get worse. Stop it now.
