This is a great explanation of trying to talk to leftists. When talking to some of the more reasonable ones, one of the patterns I've noticed is they will often not try logic, but instead a stream of "did you know..." The assumption is that their logic is sound, and that the only reason somebody would disagree with them is due to a lack of data. The possibility that somebody else could have access to the same dataset and draw different conclusions never occurs to them, because like you say their model of reality is correct by definition.
