Show them the law and they will still think you're nuts. They would rather believe in that which feeds them. By providing the faithful with a sense of security and giving comfort to those in need, the socialists have created quite a following. The control of the automobile began in the early 1900s. Many generations later these unconstitutional license laws have found favor with the converts to the socialist democracy.
Gun control is a much more recent invention.
Then came the Gun Control Act of 1968. An adult citizen could no longer mail a gun. The vine of socialism isn't about to stop here. Having sunk its roots into the Commerce Clause, it will grow to control all aspects of the gun. But only if we fail to rip that weed off the wall that is our Constitution.
