There's an interesting documentary, The Brainwashing of My Dad.

Basically rightwing media turns a normal person into a mindless hate zombie. Plenty of y'all have seen it.

It has a happy ending. Mom and dad move to Florida, and the kids just program Fox out of the available channels, and block Facebook on the computer. "Weird. Must be some problem in the new house." After a while dad returns back into being a normal person, and even chuckles about what an asshole he was for a while.
