It's such an unpleasant experience speaking to someone who has bought into some form of group-think on a topic. One of my college friends, otherwise an extremely bright guy would frustrate me immensely whenever any political topic came up. Not because we disagreed, but rather because I felt I was talking to John Oliver or whatever other pundit he recently listened to on a topic. Same points. Same statements. Same words. Discussing the root of his propositions were impossible, because they weren't his. He didn't think about them, someone else did.
