You not understanding me is not ironic. He's not a member of a primitive tribe, he's an anthropologist.
If I visit a country and they tell me I should hate homosexuals, knowing what I know about homosexuality means that doing it would make me an awful human being. Even if I respect their different opinions on the matter, it doesn't mean that they are being good, because we know that homosexuality isn't a choice more than they know it is a choice.
Vultures eating dead flesh is not inherently wrong, it's just distasteful to some. This very obvious example of child sexual abuse that actually harms someone who is alive is not even close, and it's weird that you're making that comparison. Do I really need to cite the negative effects of sexual abuse on children to justify my position here?
