> For every person and in every culture, offending people is considered wrong.

That's actually not at all true. For many people, and in many cultures, certain things are considered both wrong and proper subjects for offense, certain things are considered wrong when they are the subject of offense (and thus are also proper, while not necessary, subjects of offense), and other things are not considered wrong independently of whether some people find them offensive (and, in fact, being offended by them, or at least expressing such offense, may be considered wrong itself.)

The idea that anything that anyone finds offensive is, ipso facto, wrong is not a cultural universal, and AFAICT not held by many people at all (even people who seem in some contexts to appeal to that idea seem to find some instances of offense unjustified and unworthy of consideration.)
