Let's not confuse "moral relativity" with "extenuating circumstances"--that can get tricky. But assuming that's not at hand, moral relativity is generally bullshit in how it's applied. It usually boils down to "well it's okay because that's how they normally/usually/always do it over there" or some justification for "we shouldn't be intervening because X is just their way of life," even when X is things like throwing people in prison for being gay or granting almost no rights to women or deciding that "hey, you have not lived up to my expectations as a son/daughter/brother/sister, so I am duty-bound to kill you" or the like. On small things, like whether you shake someone's hand or bow or do the kiss-on-the-cheek business, moral relativity (if even applicable) is not of any consequence, since no one is anything more than somewhat awkward after getting one when expecting another. But when it comes to something that is actively infringing on someone's rights or actively harming someone (murder, violence, rape, any form of abuse, theft, defamation, etc), it's absolutely wrong--but, let's not forget those magical words, "extenuating circumstances." It's why things like murder in self-defense is acceptable, or stealing a loaf of bread to feed your starving family, or hitting someone because you had good reason to believe they were going to hurt you in some way.
But as pertains to this topic: trying to argue that moral relativity in the sense of "well MY morals dictate X so it's okay for me to do X" is absolutely bullshit, and people trying to pass that off as justification are idiots. Yes, harsh wording, but I stand by it. It's an immature, childish, selfish, egocentric and frankly ignorant viewpoint to take.
