I guess the only tactic is to do what many speakers at the convention did; don’t mention Obama by name only by his title or “he”. To refer to Obama’s human side is to run the risk of being called a racist for drawing attention his race. You can only avoid racist code words by trivializing the president as a human being.
It is ironic that the loudest cries of “racism” come from those who are the strongest supporters of racial preferences. Perhaps we need to differentiate between Positive Racists, Balanced Racists and Negative Racists. Oh course, if we do that then we will absolutely have to break these down into subcategories designating WHICH race(s) is the subject (object?) of the racism.
PR(N), NR(W), BR(N,W,O,H,M,P,A,H) [Hey the LGBTQRZ crowd has nothing on us!]
Finally, we have the category of Human Racist, as in:
“The whole world is festering with unhappy souls.
The French hate the Germans, the Germans hate the Poles.
Italians hate Yugoslavs, South Africans hate the Dutch.
And I don’t like anybody very much!”
