Purity

White. It is worn by the bride in weddings, it's the garb of angels.

Yet how do you make the color white? By sticking every other color in, in equal amounts at the same time. Doesn't sound too pure to me. To me, that sounds like the recipe for a really great porno.

Next time you meet some bigot talking about the purity of the white line, explain politely that in that case he/she needs to service seven people of various colors at once. If necessary, use pictures.
