But are "races" defined by the same parameters we define races in current year Earth? Valyrian being an ethnicity is irrelevant because we don't know exactly what defines that ethnicity.

All I remember was blonde, fair hair and purple eyes being indicative of Valyrian blood. Nothing specific to skin color.

Regardless I am glad you and I (and basically everyone else) agrees it's superior to how RoP handles it with no attempt to even hand wave it away with a goofy explanation.
