How do we develop social/political viewpoints? Do we just defend the things we want to be able to do? For example: Argument from person who smokes. "Stop taxing my cigarettes. That's a government intrusion." Argument from same person who doesn't like that SUVs block their view on the road. "Get those SUVs off the road. They're dangerous and bad for the environment." Instead, shouldn't we develop a consistent reasoning platform, and then base our decisions off that platform - rather than just, "I don't like cigarette smoke, so let's ban it."
