"Michael Richards' reaction, to attack a heckler based on his race, was wrong and racist."
Or do you think his response was reasonable and not indicative of anything troubling about him?
Michael Richards was not the first nor will he be the last to target a heckler's heritage (whether that simply be calling him an illegitimate "bastard").
The comment he made about "50 years ago" is more troubling than the use of the n word, as much as I may despise the use of that word modern society deems it permissible now more than ever. You will find far more songs (especially by charting artists) and films using that word than at any other era in American history. The 1930s films may have been racist in their depiction of black people put that word was not tossed around. Neither did it appear outside of perhaps some racist "Johnny Reb"-type songs.
Where do you work so I and others can do as Jerry Seinfeld did and go heckle you at your place of business?
