I feel like I need to ask:
Is it ok to stipulate that I'm all for better background checks, if you don't ever by legislation put me in a position where I am unarmed at the mercy of a criminal? Personally I'm all for people who violently protest something to have rights to weapons taken away, and people who've committed felonies, etc. I know that's not popular or legal, but maybe that's going to change. What I fail to see any of the "gun control/removal" advocates acknowledge is that mass shootings only happen when there aren't legally-held firearms. They happen at churches, at schools, at malls, at recruiting centers, at military installations, at discos and concerts with metal detectors. Personally, I feel that you as gun control advocates are doing us as a society a huge disservice by assuming that legislating "good" people's use of arms is arbitrary and can get taken away.
You know where I don't see mass shootings happen? With politicians or celebrities with protective details. Gabby Giffords did not have armed personnel escort her (for whatever reason) and Jared Loughner got off about 30 shots before he was tackled by an old Army Colonel. When Reagan was shot Hinckley was taken down within 3 seconds. He didn't have time to "mass shoot" people. When the church shooter last year in TX stopped wasn't after he'd run out of ammo, but after someone with a gun engaged him and he drove off wounded to commit suicide. The Clackamas Town Center shooting only stopped when the shooter wanted, maybe b/c guns aren't allowed there.
Personally, I believe all people have sin and evil in them that is only mitigated through societal mores and/or religious adhesion. I know that many people believe that "all people are inherently good". I don't know why the "inherently good" people have a problem with more "inherently good" people having weapons around.
