I always though "homes" as you say it was really "holmes", but being white I never really cared or bothered to find it out. But to answer your question Alex- you can say nigga or negro or darkie or even nigger here without worrying about being censored or banned for it. The difference from what you may be used to is you will have to be able to defend it's use. If you use inflammatory words just to stir up problems you could wind up banned, but before that happened you'd be set upon by the users here. I think you can say whatever you want here, just be willing do defend what you say.
