9. False Dichotomy
Like Republican and Democrat, Communist and Capitalist, Altruist and Autoist, the binary opposition of Liberal and Conservative cuts humanity into two and only two competing camps, and most people fall squarely into neither. So if you see someone complaining that “Liberals think X” or “Conservatives think Y”, before you protest that you are Liberal, and you don’t think X, or you’re Conservative and don’t think Y, please reconsider. You may not be as Liberal or as Conservative as you think.
