A collective well organized police state backed by public sentiment against someone with a 3D printed gun is no assurance of liberty.
I'm not anti gun but it's just salesmen hiding behind a noble sentiment. The only thing the NRA ever bans are generic after market add-ons which make cheap guns work like more expensive ones
A technology that reduces the profit margins of gun manufacturers, that's the quickly banned object.
People can buy what they want, whatever. The thing I actually don't like is marketers underhandedly trying to sell me things by waving a flag in my face.
Then people act like consuming a product somehow counteracts system upheaval, give me a break. Any strategic despot would get the gun owners to work for him through packing and cracking the party support and spin the tyranny as protecting liberty. Many gun owners would need very little convincing that they're "liberty defending foot soldiers". That's how this game plays out.
