The "If Criminal, then Bad Person" and the "If Bad Person, then any Bad Thing OK" combo are pervasive in America, across the political spectrum, and have been for a while. At least since the War on Drugs started, and almost certainly well before that. It is frightening to have a conversation with a seemingly well-meaning, moral person and have them casually joke about prisoners being tortured, raped, or killed. I don't think it's an attitude unique to America but I think the private prison industry has had a lot to do with how incredibly common the attitude is that, if someone is in prison, they must have done something wrong, and if they did something wrong, any bad thing that happens to them (forced labor, starvation, sexual assault, death) is deserved punishment. It's ghastly.
