I'm a 50 year old Veteran (USMC) with about no experience with Video Games, but I agree with most of your points- though the 'Semi-Autos as a new NFA catagory' just doesn't work for me.
I can't believe I am going to say it, but I would be OK with closing the 'Gun Show Loophole'- PROVIDED that the NICS system gets upgraded, and made more freely accessible. I think I'd even be OK with a NICS check for bulk ammo purchases (over 1K at a go?) (again, with a better NICS system).
I'd accept a federal level of firearms law to supercede the current mish-mash of state laws- I live for parts of the year in RI, NY, VA, and FL, (and I was in NJ for a good part of this past summer) and frankly, I think I have committed felonies just driving from location to location.
And I do think that regardless of what Pres. Obama might want in his heart of hearts, he knows that we cannot afford the resources required to confiscate 300 million privately owned firearms. I also noted his signing off on Carry in National Parks and Transport of firearms on AMTRAK as being more pro-gun than anyone expected.
Thanks for sharing this- I want to come back to it and consider your points in more detail when I've a bit more time.
