In response to Heineken's pretty racist ad for their light "beer", I am boycotting their light "beer". Oh, wait, not exactly much of a move on my part. Come to think of it, I can boycott just about everything they make without much of a sacrifice. We might infer that super-edgy advertising might be largely the realm of companies that really don't have very many good products.
I am left, really, to make a difference for race relations doing something else besides boycotting light beer.
