They are essentially conspiracy theories for the most with the exception of climate change. That's one important way to think about the left. They're mad conspiracy theorists and they think just like them. One of the flawed ways of thinking any person into conspiracies gets into is the ability to take two nominally contradictory facts and determine both as proof of the conspiracy.

For instance when the cop who had his taser stolen at the Wendy's is acquitted -- as he should be -- or the boys who chased down the 'Jogger' are let off the left will be screaming about how this proves how racist our system is but if they were convicted it would not prove to anyone on the left that the system is fair. It actually doesn't matter what happens the theory is sound for them.
