"Oh, it's okay. No harm will come to the law abiding gun owners, until we decide to just get rid of guns and lookie here... we have their addresses and family information right here when we need it."
I am all for responsible gun control, but all it takes is one nutjob to push beyond the "honest intentions" of something like this to cause a military-like situation where civilians begin getting apprehended if they don't turn over their weapons. It has happened before in history... in a rather infamous country during the mid-earlier 1900s... *sips tea*
Slippery slope argument. Bullcrap. *sips tea*
