Right, I think you're spot on. There you have it, of course It's the media. Foxy news is probably one of the most, if not THE most, influential and highly effective brains laundry of the easily manipulated mass simpletons, even if a tiny minority does not need that push and is convinced out of well calculated interests or due to dedicated political ideology.
They literally live in a parallel universe. That's why the division is so stark. There's no common discourse or something you can start a dialogue on. Fox runs its own version of headlines, with usually little in common with the rest of humanity, and the hordes are in lock in that world.
