It depends what you mean.
If the purpose is simply to offend someone for no reason other than to upset them then that's just being a **** and you shouldn't be surprised if the response is a headbutt.
It's ok to say something you know will offend others if you believe that it serves a more important purpose. I'd try to avoid offending people as much as possible out of politeness, but reserve the right to do so if I consider it necessary.
To get a point across, mainly.
It works for both sides but I guess that would make it a non-biased reason.
