I guess it’s an indication of how snowed the left is that you can actually find people today acting like the U.S. withdrawal from the UN Human Rights Council is actually some sort of real affront to human rights.
Maybe they don’t know the council is led by human rights bastions like Iran, Cuba and Syria. Maybe they are so clueless that they really don’t see what the problem would be with that. But in all likelihood it’s simply a matter of a narrative working the same way every other left-wing narrative works. “Human rights”? Good! Trump quitting? Enemy of human rights!
