Doug,
This subject has become so polarized that it seems impossible to find any article that does not take a position on one side or the other. I don't use Wikipedia that much - usually look for a more reliable source. Is there a way to check the numbers that the article mentions, ie. 5,428, more than 500 and over 2,000?
