A friend of mine once remarked that it's good to have an open mind, but not so open that your brains fall out.

In a world with almost seven billion people, there are many folks who believe that Darwinian evolution is a fraud, or that 9/11 was actually a Mossad plot, or that astronauts never actually landed on the moon, or that Henri Philippe Pierre Marie d'Orléans should be the absolute monarch of France. I see no reason to waste my time giving these "theories" the attention required to even refute them.

I don't care how much of a bold and contrarian and politically incorrect thinker you are--at some point you have to draw a line and say that certain ideas deserve to be ridiculed because they are, well, ridiculous.
