"Racist" Political Cartoon

After the outrage spawned by the infamous chimp cartoon a few months back, we should have known it was only a matter of time before someone cried "racist!" in reaction to a cartoon depicting Judge Sonia Sotomayor:

One of the more controversial aspects of the cartoon is that it contains references to Mexican culture - the sombrero and the piñata - while Sotomayor is in fact Puerto Rican. Such ignorance of the subtle differences between latin cultures is undoubtedly indicative of racist intent, especially when Sotomayor has on countless occasions sought to portray herself as a representative of Latin Americans in general rather than simply those of Puerto Rican ancestory.
