A dynamic face of the New Republican Party

Joe the Plumber is the gift that keeps on giving. He seemingly advocates shooting people who "didn't support our troops," as "they did back in the day." Now, I have no idea who "they" are, or in what day that transpired, but it's certainly not recently. Here's the transcript from Think Progress:

Back in the day, really, when people would talk about our military in a poor way, somebody would shoot ‘em. And there’d be nothing said about that, because they knew it was wrong. You don’t talk about our troops. You support our troops. Especially when our congressmen and senators sit there and say bad things in an ongoing conflict.
