Advocating the licensing of ANY aspect of gun ownership - concealed carry, machine guns, silencers, handguns, short-barreled rifles or whatnot - helps codify the 2nd Amendment as a privilege rather than a right.
I couldn't agree with you more! I believe any form of restriction is "infringement".
Viewing the 2nd Amendment as a privilege works for those who see the U.S. Constitution as a living document that needs to be perfected, rather than a legal document that means just (and only) what is stated within. It starts there, then the other guaranteed rights are also privileges that can be abridged, or eliminated.
“... the right of the people to keep an bear arms shall not be infringed.” So easy even a democrat should understand!
