Marketing is really just a reflection of the society it's made in. If the bigwigs at Pepsi didn't think that we'd accept it and in fact be so drawn to their clever racial-specific marketing tactics, then they'd just pick some other idea from their ad agency.
You can either "vote with your feet" and drink Coke as a punishment to Pepsi, or you can buy a Tivo/Media Center PC and skip the commercials altogether.
