True. I am not interested in showing that it is density or demographics (I don’t think I could do it). This was sloppy on my part:
I should have just said lots of other possible explanations exists including density and demographics (which IMO is more believable, but I can’t prove it). By showing other possible explanations, it shows that his claim needs further proof before it is reasonable to believe. I should have stuck to that line of reasoning, but got hasty.
