Oh yes, race is far deeper than skin. Or are you one that believes it's a social mirage?
I believe race is a complex thing, which includes elements of biology but also langage, social elements, the history of a community, its expansion, régression or homeostasis. Some culture aim for conservation while others have expanded, sometimes failed, sometimes succeeded. I would object to being called a racist. A racialist of sorts though not in the 19th century definition.
