I seriously doubt it would get this far, but even if the government was successful in passing this and shutting down forums/communities they(the communities) would move to the Deep Web like the Silk Road. If you shut one down a dozen more will pop up in its place and you would see a revolution and greater congregation of firearm owners and enthusiast across America(that is one group the bureaucrats do not want to piss off). Of course I don't think that the law would pass constitutional muster in the first place....but like I said, let them try. /post that puts me on a watch list.
