The film Borat that recently hit the cinemas in the US manages to present an "ethnic" offense but this time addressed to mainstream Americans who are a sort of ethnic specimen. Clearly authors of the film abused their naive and willing subjects who did not realize they were interacting with a caricature of the outside world and were patiently condescending toward the Kazakh pretenders.
I object to the abuse, even if it is abuse of ignorance and stupidity, but maybe something good will come out of this. Also the film is a joke in bad taste - but I do not object to that.
