The UN needs to STFU because they don't know what they are talking about. It's like passing a law saying no one shoot unarmed people.
This is an old Marxist group that I think has been around since the time of Stalin. Back then the Reds were not very astute when it came to naming their front groups. They always included the term "Union" somewhere in the name, as in "American Civil Liberties Union" or "Union of Concerned Scientists," etc.
