Right or wrong have absolutely nothing to do with it. It can't, because without a universal morality any notion of universal "right" or "wrong" evaporates. This is about refusing to tolerate another culture not because "it is wrong" but rather because it is beneficial to you to do so.
Your problem here is that you seem to be assuming some sort of universal "respect the right of others to coexist" or "live and let live" morality, where you should not stamp out other cultures unless you have determined that they are "wrong". This sort of universal tolerance for other systems of morality does not exist. It really simply doesn't; history would be far less bloody if it did.
People that do not believe in universal morality are still very capable of acting only in their own best interests, at the expense of others. Egoism is not incompatible with moral relativism.
