If it had people of different color of skin but all men, would that bother you (no women)?
Or if it had different color of skin but all of them were Christian? ( no other religions)
Or different color of skin but all Canadians would that bother you? (No other nationalities)
As a European I am much more used to diversity meaning national or religious diversity. Still getting used to this notion of it mainly been used in the context of skin color in US.
