When I took a cultural anthropology class many, many years ago I believe "race" was divided into three categories: Caucasoid, Mongoloid and Negroid.

Precisely - and it was total nonsense, based on a pseudo-scientific theory invented by racists, and promulgated by racists.

Any suggestion that there is such a thing as a British "race", which is to be distinguished from a British nationality is, in effect saying that there are some people who have British nationality, but who are not British by race. And that is rubbish and it is racist rubbish. And there are people who think and say that kind of thing. I doubt very much if any of the people who have contributed to this thread actually believe in that sort of stuff.

You don't have to be "a race" in order to have a common loyalty and identity. Obviously there are a lot of people for whom the sense of being British is enormously important. But being British doesn't mean belonging to a British race, any more than being Catholic means you belong to a Catholic race, or being a Mudcatter means belonging to a Mudcat race.

As for Ferengi - they should leave the racism to the hew-mons. There's no profit in it.
