Well, I sure didn't read anyone even remotely suggest such a thing, it would be almost impossible to do it, and if you could, it would take decades for anyone to round up the guns. The number of guns owned by civilians in the United States is between 238 million and 276 million, which in a country of 300 million is pretty damn close to a gun for everyone.
It's not the right to bear arms at the center of most gun discussions, it's how they are used
And what use is that? How many real uses to they have? Sure, if people were making lamps out of them, or using them to hammer nails the anti-gun people might tone down a bit, but the reality is that a gun is a machine. Like all machines it's designed to do something, and what they are designed to do - and they do it very well - is kill things. Handguns in particular a machine designed to kill people. Any other 'use' is just so much BS.
