Why do liberals call it a social construct?
When they say 'race has no biological basis in reality' do they mean 'race as the social construct implies it is has no biological basis in reality' or just plain denial?

Also, new here. LOL @ libfags failing (>>34) and derailing the thread. What kind of psychopath can think that there is no such thing as race when you can meet a Black person you've never seen before and identify him as Black without fail, and same with East Asian and Whites?
