Once again you simply resort to insult rather than evidence and I notice your argument is shall we say fluid. It suits you to change it as the thread evolves. You claim there are no biological differences between races and then later you claim that
there is no biological basis for defining races. I like the way you subtly refined your premise since you refuse to offer any counter evidence and instead resort to hurling insults and simply restating that you are right "by God".
Now you claim that humans may be classified by race according to physical characteristics. If so please define that for us since you disregard the notion of biological differences.
