Consistency

Why do I pursue consistency arguments so much? Partly it's because I think consistency is a virtue, but mostly, it's because I'm lazy - they're just so much easier to make. If you start a normal argument, chances are that it will end in axiom lock; it's far easier to just accept your opponent's axioms for the sake of argument, show how they are acting inconsistently with them, and let them worry about the resulting mess.
