The next law will be, present your “Not A Wacko” ID card to rent a firearm.
Why would you need a card?
“I could live with a generic firearms owner card (”not a criminal”) if it meant that I could buy whatever I wanted without anyone in the government ever know what and whether I bought. Including machine guns.”
And what stops you from doing that now? The bad guys do it all the time.
That is a specious argument, and proposing any ‘permission’ be granted to exercise your rights is totally bogus.
The language is very clear.
Either you believe that you have ‘rights’, or you don’t. Compromise is not a satisfactory goal.
