[West Ender]

The word nigger was originally a pronunciation of "negro", hispanic for "black", in the accents of the Southern states of America. While obviously racially motivated, as defining a person by his colour, it wasn't any more abusive than the whole system of which it was a part, i.e. slavery.

So, for a start, these cretins were obviously ignorant of the fact they were calling you a white black-man. That the word has now become racially offensive and is only used offensively is not in doubt. Its modern connotation is only used as an insult so, yes, make a complaint and don't back down. We must not tolerate double standards and the charge of racial abuse must apply to all.
