MF is a pay-to-post site, so it is skewed towards people who will pay. It's the same as those small elite colleges where people will study something impractical for an exhorbitant fee. You would
only pay if you agreed with whatever the orthodoxy is. And it becomes self-selecting, and self-perpetuating. The people on MF are the sort of people who would say "OMG I can't believe anyone voted for Trump, because nobody I know did"
