I think it's much more complicated than that. I hate it when people like Littlejohn and his ilk use it to rebuff any attempt to be fair and tackle discrimination. Thank God we are not still living in the racist, sexist, homophobic 70s. But I think it's also fair to say that political correctness has a lot to answer for. If you look at the ideas behind communism they were quite noble, high-minded and unlike the corrupt reality they became. In a similar way political correctness started out as a way of getting people to understand how language can entrench prejudice and social divisions. Quite true. But it has now become a dogma whereby people communicate in a kind of doublespeak reminiscent of Orwell's "newspeak". Rather than helping society to be fair to all races and minorities, it increases the gap between what people say and what they actually believe. It breeds resentment because it papers over untruths with other untruths.
