Is it racist to be proud of your aboriginal culture?
Is it racist to be proud of your white culture?

Is it racist to say that Aboriginals have an inherent bond to their country? Is it racist to say aboriginals make good footballers? Is it racist to say aboriginals are prone to alcoholism?

The problem I have is that it seems to be racist to attribute positive attributes to whites. It is not racist to attribute positive attrributes to non whites.

If attributes can be attributed according to race surely this applies to both positive and negative attributes.
