Second Amendment rights have nothing to do with sporting activities but rather were intended to do with arming the public to protect themselves from a government gone astray.
Yeah, but that was then, this is now. Anyone fantasizing about defending himself against government with an AK47 or AR16 is deluding himself. In Iraq the effective insurgents are using IEDs, car bombs and remotes. The brave fools with piddly assault rifles who go
mano a mano against Blackhawks, armored vehicles and modern troops win nothing but a quick trip to meet Allah and their 72 virgins.
In 1775, there was little difference in weaponry between Yanks and redcoats. Chinese junk assault rifles may be okay to defend against the occasional midnight intruder, but today's 'armed citizen' is no match for the professional soldier.
