No, racism is discriminating based on (perceived) race, not merely the belief that race exists. (Which it manifestly does, <i>as a cultural construct</i>.)<p>Nationality and ethnicity likewise exist as related, but usually distinct, cultural constructs to race, and we have different names for bigotry based on them. Though, obviously, the distinction between these forms of bigotry is somewhat nitpicky, and often not meaningful, and a lot of time &quot;racism&quot; is used broadly to refer to bigotry based on race, ethnicity, or nationality.
