Discriminating based on nationality is only "discrimination" in the sense that you're differentiating between two groups of people, and treating them differently. It's not bad - unlike discriminating based on race. GP clearly meant "discrimination" in the discriminating-against-a-protected-class use of a term, which discrimination based on nationality is not.
