This could explain much. Why oral sex is not sex, why abortion is not murder, why a man and a man can be married, why raising prices or taxes raises revenues, why its wrong to kill a murderer yet okay to kill an unborn, why its wrong for a conservative to have an affair but okay for a liberal.
Sounds like liberals have the contrary-contradictory gene. We all see and hear the same thing, but the brain makes them say it is the opposite of what it really is. And my observation makes me sense that there is some sort of pleasure or faux enhancement of self-esteem which reinforces their contrariness.
Ha ha! All the liberals I know do seem to have a propensity for doublethink!
