One could ask the same question about things like United Nations Human Rights Council. The answer is that money, and representation of all governments is what counts. It leads to rather absurd outcomes.
Friends close, enemies closer. The UN has a long history of trying to promote human rights through engagement because it is generally more successful than the alternatives. Trying to overlay interpersonal morality onto geopolitics leads to some pretty dark places.
True. I mean in reality though, there would probably be very few countries on the UN HRC if the position required being holier than though.
