TONE DEAF OR JUST STUPID?

I pointed out to some wingers on this Politico thread that the Tancredo/Buchanan faction of the GOP has turned and will continue to turn away Hispanics. They disputed this claim and have so little self-awareness that they can't see how offensive this statement is:

This might sound racist, but Hispanics need to stop having so many children, I'm from San Antonio, I know what I'm talking about.
