The media intentionally conflates two separate issues. Everyone, including the NRA and GOA, agrees that convicted felons and those adjudicated as mentally incompetent should not be able to purchase firearms or have access to them. The President supports measures that will make it possible to enforce this existing laws.
This is completely separate from the liberal agenda of restricting the right of everyone else (i.e. non-criminals of sound mind) to keep and bear arms of their choice. The media strategy is a bait and switch - making sensible people think they're talking about the first when they're really talking about the latter.
everything hinges on who gets to define “sound mind” and what due process surrounds those who fail to meet that bar..
