Your argument is based entirely on your own anecdotal evidence which means it is very weak as far as any kind of objective proof goes. 

I can give plenty of personal anecdotal evidence of non-WASPs being racist towards people of colour. In fact I can give anecdotal evidence of black people being racist against other black people based on what island they come from in the Caribbean. 

That doesn't mean I can make sweeping generalizations as if they are objective fact.
