This is really just another example of the ad hominem fallacy, arguing that since I was born in a particular place my ideas must be wrong. It's possible that if I was born in some primitive tribe I might be illiterate, does that mean I can't read now? Or that you can't tell if I can? It's possible that if I were born in Berkeley or Siberia I might have never been exposed to any of the learning I have benefited from on the arts too, but who cares where I was born? What matters here is whether or not what I am saying is true, and that this argument is just a way of avoiding addressing that question.
