People use 'racism' to mean 'bigotry' in general these days. Whether you accept this or not depends on your stance on prescriptivism vs. descriptivism.

I guess it is more aptly called bigotry. I was thinking along the lines of cloneship being a physical property of someone that's inherent to how they're produced (like how a newborn is probably going to be Black if its parents are Black) but the more I think about that the more it doesn't really apply because clones can really be any race.
