Race and Skin Color

Some people find the fact race is more than skin deep to be novel, when really I think it's more accurate to see races as being different enough that it extends to superficialities. So different you can tell simply by looking.

Yes, the differences dont stop at the skin but you can still tell by visual differentiation. There is no contradiction there, the presence of superficial characteristics which can be used identify something does not mean the differences are just superficial. I repeat, you can tell by superficial characteristics but they arent the only differences.
