Agreed, same rules apply.

The article also touched on a point I wish were raised more often, the racism implicit in so much cultural relativism. Try telling your friends about a small district in, say, southern Germany, where since the Crusades innkeepers have been inviting guests to have sex with their daughters (or any other awful story you'd like to make up). Explain to your friends that it's quite beautiful how this culture has lasted for hundreds of years, and that apparently the women don't mind, as it's part of their culture.

I guarantee you: where the women are white, the it's-their-culture crap won't fly. Bring the skin reflectance value down to below 50 though, and suddenly all manner of enormities get the pass.
