I disagree that the extreme left is growing at this point in time. But even if they were, there is a HUGE difference in the fringes nowadays. Back in the 60's and 70's, the leftist fringe WAS violent to varying degrees. Their desires to off the pigs is most like these lowlifes in Nevada. Now, the lefty fringes aren't violent, for the most part(of course their are exceptions, but violence isn't the goal). OWS didn't have people gathering with guns, threatening to blow the cops heads offs, like these lunatics in Nevada. The lefty fringes want to disarm.
