The argument is that NYC, NJ, and California pass ridiculous laws that do little to stop crime, but make it harder to follow the law if you have good intentions. They restrict, in some places completely, the right to bear arms. Therefore, they restrict your freedoms. If you don't care for the freedoms enumerated in the Bill, that's your problem. If you think the 2nd should be repealed, then repeal it. Anything other than the reasonable restrictions SCOTUS has determined are violating the constitution. And there are lots of laws in the states mentioned that are far beyond reasonable.
The FUD is spread by anti-gun people who call for bans on the misnomer, "assault weapons" (which account for 1% of US gun deaths), additional loopholes that only law abiding people will follow in the first place (written permission to travel, no CCW, etc.), they are ones that ignore the recently released CDC and Harvard reports that show an overwhelming amount of defensive gun use every year, and they completely ignore the tragedy of gun free Havens like Chicago. While guns do make it easier to kill, the killing problem is a cultural problem of poverty and inequality, not a gun problem. The FUD is spread by both sides.
