I absolutely reject you accusation in the most strongest of terms. Especially the tone with which it was made with the amplifier "and you know it"!
The discussion was, could there ever be an invasion possible form CANADA or MEXICO when the United States has a below par defense budget (refer the posting below from Chuck). I suggested that perhaps Mexico has already entered the United States legally and illegally. That has ZERO to do with racism. And is a fact. I can only wonder why you would think racism if I mention Mexico migration? Can it be because racism is in the eye of the beholder?
If I had said the same for Canada, would you have thought differently?????
