I don't particularly disagree with your moral relativism. But I will point out that there are obviously axioms we can base our beliefs on (be they "harming people is bad" or "gods are good so do what they say") and we build up from them to a point were the underlying reasoning is lost and actions can be viewed as both good or bad so obviously reasonable people can hold different views. However the issue with saying we shouldn't be intolerant of intolerance is that nearly everyone agrees that we don't have the perfect world. You're asking us to break the feedback loop when we know things aren't right. Perhaps you're just arguing caution before deciding to boycott and argue for a boycott, still I would argue the action is not unreasonable and it is derived from a basis on very sound axioms.
