Even in those bastions of liberals like Chicago and D.C., we're seeing changes in the anti-gun attitudes of old. Regular folks are becoming disgusted at not being able to defend themselves from the thugs who don't care about laws.
2nd Amendment says that the right of the people to keep and bear ams shall not be infringed.
You may be ok with having your rights infringed, but I'm not. Full auto weapons and short shotguns are particularly useful arms for a militia, they shouldn't require a license.

” Why would it be a problem for a state to ban the sale of rocket propelled grenade launchers, or fully automatic weapons?”
It is a problem because those same states would be the ones crying for gun control now- they implement it, they fail, they blame the rest of the country for “lax gun laws”, and then attempt to destroy liberty for the rest of us by manipulating the Federal government.
The problem comes with the perception that any thing a state can do, the federal government can do.
