dinavan, you are implying that if race means nothing, that racism means nothing. In genetic terms, race has never meant anything as regards humans. In terms of people's responses to perceived differences, race and racism still are among the most potent destructive forces in the world. Ask anyone over 50 in Alabama, anyone over 20 in Bosnia, ask in Rwanda, South Africa, Bradford, Paris or any of a thousand other places.

So NOBODY is a member of a race other than the Human race, but of course people can have racist reactions to the alien they see in others. I can't tell a Serb from a Croat, or a Hutu from a Tutsi, but they want to and can. I dare say that the hypothetical visitor from Mars couldn't tell a Swede from a Bushman without careful study.
