Berm Bandit, apply the same to the world nigger - it needs no debate. If you are attempting to denigrate someone by using it, or are just pain ignorant, don't.
If you read what I wrote, in the context that I wrote it, what I said was that the actual fact (well documented) that Guy Gibson had a dog called nigger, at a time when that word did not, in this country, carry the racist overtones that it does now, and the fact that, that was accurately reflected in a film also made at a time then the word did not carry, in this country, the racist overtones that it does now, does not make the film, the Dambusters, racist. In fact to try to pretend that it is out of some warped sense of political correctness is if anything gravitating straight into the hands of people like Nick Griffin, who no doubt would love to jump onto a situation whereby a national war hero was branded a racist by some "loonie leftys".
That is not to say that if similar circumstances were to occur now, and say for example Prince Harry had a Black Labrador and it called the same thing, that that would be acceptable. See the difference?
Good, now move along theres nothing to get on your high horse about here.
