In a blink of an eye Americans went from "the government is out there to oppress you" to "if the government says the undisclosed people it snatches from the streets and deports are criminals, it must be true".
It's not necessarily an american thing. People will always have biased towards whatever fits their pre-conceived notions, and we seem to be in a post-truth society.
Ironically, it's not focused a lot more on feelz, no realz. People don't seem to want to remember that reality is in fact, often disappointing.
