I agree that this type of article does attract racist comments and that is inevitable.  Someone could write an article on world peace and the same thing would happen.  You will always have those types of ignorant, hurtful comments.  

These upset me of course, but no more than the politically-correct censors who -- in trying to prevent those types of offensive comments -- also end up stifling intelligent discourse among responsible citizens who actually care about the world they live in and want to make it a better place for all.
