To those who don't know or remember the genesis of this: It started with Occupy Wall Street. Leaders/speakers would use loud speakers to communicate with the crowd. When they wouldn't leave, the city reached the point of shutting off access to electricity. In what I thought was a fairly clever move, they started to repeat what the speaker/leader said so those in the back could hear the messages. However, after they had the electricity back on, these useful Idiots, not understanding what the point was in the first place, continued to repeat whatever the leader said. They then continued to do it at all protest type gatherings since. I doubt that any of them could tell you why or how it started at this point. Welcome to the generation of no critical thought.
