FS can you enumerate with specificity what changes you oppose, and what changes (if any) you favor?

Please address the following:

Mandatory background checks for ALL gun transactions with a ban on convicted felons and crazy people from getting guns.

Limitations on magazines.

Banning certain types of "assault" weapons. On this one even a bleeding heart liberal like myself has a problem with the myriad "definitions" floating around out there. I mean no one wants people to have nuclear weapons, tanks, rocket launchers, etc. Where do you draw the line ?
