There are two kinds: Callanians and Non-Callanians. The former are mostly individuals, but pay for this by having much more severe moral standards applied to them.

Non-Callanians, on the other hand, are defined by single traits. Which is not racist at all. Obviously.

Of course, there are still single individuals who break with their races customs and redeem them that way, because, even though other cultures' traditions are great, they can't possibly be as great as our own, right?
