I was taken back by the Coke commercial, but the remember that Coke is sold all over the World and was played in 170 countries.
At first I was going to say that the people watching in 170 countries are tuning in to see American football and American culture, but then I remembered that the commercials in the other 169 countries are controlled locally, i.e. the rest of the world is NOT necessarily seeing our commercials. Either way, your feeble attempt to rationalize Coke's offensive commercial doesn't wash.
