"Now I ask you one more time: WHAT IS THE DETAILED EXPLANATION OF THE REASON FOR THEIR PROTEST?"

               This is just a guess, but I suspect the protestors are concerned about the fate of the planet, and they don't think a tiny group of self-appointed elite individuals should be in a postition to tell everyone else what to do--while extracting the fruits of their labor and banking it in corrupt institutions. Just a guess, mind you.
