(I expect that my interviewees found some of my core beliefs equally jaw-dropping.)
Yes, yes, yes.
My father-in-law got frustrated today talking politics, and he goes, "Why can't people just understand what would happen if Hillary was elected? You don't have to be a rocket scientist to understand how it would destroy this country!" (Actual quote). He literally could not comprehend how other people could think differently than him, and it was frustrating him almost to the point of tears.
I don't talk politics around family anymore because there is no more reason, no more logic, no more looking at a data set and discussing different ways of interpreting it. It's just "I'm right, and anybody who doesn't agree with me is a moron."
I think a lot of people fall into this trap because challenging your own belief system might be one of the hardest things on earth to do. When you come out on the other side, however, it's worth all the pain and suffering. You either reinforce what you thought was true, giving you even more conviction. Or some of your old weak beliefs are cast aside for ones that are better.
It's funny how we'll go to ten different websites to look up reviews of a product we want to buy, but we won't do the same to figure out all the angles of a news story or politician.
