You posted the link about Islamic State - not me. And what human heritage was exactly destroyed by this protest where the protestor glued his head to the painting? And what human heritage was destroyed by other climate activist, like the one I mentioned in the previous comment, i.e. the scientists protesting or school children protesting?
