Race Is a Social Construct?

Political correctness these days claims that race is socially constructed; perhaps it goes further to say there is no objective, independent basis for race.

I tend to bristle at such claims because I believe groups of humans can be grouped by common genetics.  But regardless of that, things like this Tweet remind me that society does construct "races".
