So? Skin colour and body shape are determined by environment as well as by genes, and race is determined by social factors as well as by skin colour and body shape. It's at least as convoluted a process to get from genes to race as it is to get from genes to wealth.
You're accusing me of politicizing facts, but seeing race in and around normal human variation is itself a political act, even if it is an innate prejudice.
It is dialectically true that "social construct" and "figment of the imagination" are two different things. It is rhetorically false; in rhetoric calling things "social constructs" is clearly an attempt to simply label them as figments of the imagination.
Huh. You really believe that people who say that race is a social construct are trying to label it as a figment of the imagination? That's not my intent, at least, and I doubt very much that it is the intent of anyone who makes that claim in good faith. I'm not trying to argue using rhetoric; I'm saying that if one tries to segment human variation into races ignoring societal attitudes, one will either fail entirely or will arrive at "races" that do not correspond neatly if at all to society's conception of race. That is the sense in which race is a social construct.
Sad thing about humanity - we love to politicize facts and deny reality because it doesn't match some ideology.
