How many white people have noticed, certain words infuriate the world, but , and others are not mentioned

The words Michael Richards used are not ones I ever use, but I do resent that no one is objecting when whites are denigrated, and called ethnic slurs? And it just doesn't die down, when it's non-whites, being labeled. For whites, (who are usually a Heinz 57 mix, by the way) it isn't even commented on!!! Why???? Why don't more whites object publically? Or, conversely, why do so many other ethnic groups??? Whites are rapidly becoming the minority.
