I honestly think that the celebrities list is a bit.......overinclusive. I think they went so far as to include any actor who has starred in a role in a film that was anti-gun, or made any comment like "I would never own a gun" or "Guns scare me to death" but would not and DID not actually support restricting anyone else's rights. Just because someone isn't as pro-gun as we are doesn't automatically make them anti. On this site, WE can't even agree on everything.
If I pulled the plug on every celebrity who doesn't agree with me politically, I would have a very short list left. What I DON'T support is celebrities who start to think they are more important than they are, and do things that endanger lives. (Sean Penn going to Iraq and Jane Fonda come to mind.) But even as extreme as Alec Baldwin is, he's still among the best at what he does and is still able to laugh at himself.
A few years ago I saw Concrete Blonde at a club in SLC. In the 80's they did a song called "God is a Bullet" about gun violence. I have a live cut of the song where they dedicated it to the LAPD. When I saw them live, I got to talk to them after the show, I was talking to Johnette Napolitano, I broached the subject, and she said that she hates violence, but it was mostly directed at those who abuse authority, not people who own guns. It's not her thing, but she doesn't tell people how to live their lives, just not to hurt each other. Not exactly on our side, but not on the Bradys' 'special list' either.
