I actually don't really agree with him.
I agree with the science he references but I don't believe I should tell someone I am a "sapien" every time someone asks me what my race is.
Most people just want to discuss common sense and are not asking me for a lecture in biology when they ask me my race.. having said that, most people I know tend to say "Where are you from" or "What country are you from" instead of "What is your race".
