Why is a gun registry a huge problem? What happens when you get a license plate for your car? Do they give you a random plate so you can't be traced? What about the serial number engraved in the chassis of your car? The serial number of your computer parts? Why is it okay these things are on record but oh noes, god beware someone knows you own a gun? 90% are probably going to post about their nice new "toy" somewhere on the internet anyway.
