It's only 'wrong' because of particular religious belief via tenants that say it's wrong that we have been taught which now seem to be universal knowledge because we're simply human..?. It's not wrong in the Middle East to stone people etc. Or even to enslave people in the Sudan! I think some miss that fact and think that we would still think certain actions wrong in the West had we never been a Christian Nation. You should listen to the psychological explanations by Jordan Peterson about what the religion actually means biologically and psychologically to us. It seems like some dismiss religion too quickly and maybe understandably due to a negative personal experience with institutional religion. But I think there's much more to it.
