When wrong is right

The context is different, so the word carries a different meaning, I was told. Well, a wrong is a wrong, if you ask me - and it's not because the Queen of England says it is right that it becomes right. Anyway. The context is what determines whether a word is right or wrong. Does that mean that, if I call someone a bitch or an asshole, will it be the context to determine whether it shall be offensive or not?
