If they can get you asking the wrong questions, they don’t have to worry about the answers.
— Thomas Pynchon, Gravity’s Rainbow
A great deal of leftist sophistry is founded upon faulty, yet unexamined, assumptions. If a leftist can trick someone into buying into certain assumptions, then the erroneous conclusions that follow from those assumptions are a simple matter of logic. This is part of what makes their nonsense so pernicious. The vast majority of people are simply not perceptive enough to see through to those assumptions and realize that they are bunk. Some will intuitively sense that they are being had, but there are many who will not, especially if they are surrounded by it every day. It is unfortunate that too few people really try to understand things.
