Troll? Hardly. That poster is a lot more protective of A2 than the NRA who he is criticizing.
And what has he done? Is his name on any lawsuits against the San Francisco council? Yes, he's a Sarah Brady troll. He can't use any point of view that isn't over thirty years old.
He can't answer the question if the NRA isn't there, who would be? Another gun group that hasn't done a single solitary thing on their own since their existance?
