Two months ago, I satirized the idea that it might be possible to deny that the color green existed.

This week, Tom Tomorrow satirizes that some might deny that human sexuality existed. (Link goes to Salon.com; Day Pass required.)

And then there’s those that deny the fundamental organizing principle of modern science. Oh… wait. They don’t intend that as satire. My bad. Those folk really would deny green or human sexuality if it meant they’d gain power.
