it's puzzling what makes some parts of US society so vulnerable to someone like Trump. The kind of fundamentalist religion popular in some parts seems to have something to do with it, a lot of the teaching from those churches seems to be not just anti-intellectual but anti-thought. Other Trump supporters seem to fear the imminent appearance of a communist dictatorship, and that fear seems to give people's brains enough leverage to make it seem ok to believe all kinds of nonsense, a kind of trade off that enables people to support Trump and feel good about it because in their mind they are fighting communism by doing so.
The conservative media plays a part in it too, it seems to me. There are some decent conservative news outlets over there, but the popular ones hold a lot of the responsibility for the dumbing down of political discourse in the US, reducing everything down to basic notions that force people to choose between imaginary notions of right and wrong that have little or no actual relevance to reality. But I suppose that is a chicken and egg question, do people watch that junk because it gives them pre-packaged opinions, or does it exist only to echo those opinions?
