Agree wholeheartedly with the "Precautionary Principle." Argue fervently for the passing of national laws enforcing the wearing of tin foil hats as a precaution against the possibility of aliens from outer space trying to probe their body orifices. Argue for a massive government spending program to build mighty death lasers at strategic points around the United States, so as to stave off possible alien invasion and/or asteroid strikes. Say: "It might never happen. But it's like global warming: the hazards in the very unlikely event that it IS true are so great, we simply CAN'T AFFORD NOT TO ACT!"
