Imagine being a newcomer coming to this discussion and the two sides are "debanking is bad and hurts people" and "the Universal Declaration of Human Rights is garbage."
That the UN General Assembly endorses a document is no more valuable a signal than BRICS, the OIC or the Arab League doing so. If you want to point to a document for its moral weight better not to point to one from an organisation that has Saudi Arabia chairing its women’s rights committee.
