I just realized this very simple fact. Nothing is lie-proof. Everything is corruptible. Just because an argument is airtight, waterproof, bulletproof, indestructible, logical, reasoned, rational, and otherwise perfect, that doesn't mean you can't destroy it with one little insignificant gnat of a lie. Any ignoramous, any five-year-old, any piece of shit can play the Lie card and win the game.
Think about that.
