Please tell me that you don't consider the later appropriation of "Let's Roll" to somehow mean that people like Neil Young had committed the original sin of supporting the wars. By that logic, is Todd Beamer guilty of the same?

It's startling the ease and quickness with which some people will see a way ascribe some perceived right-wing guilt to someone like Neil Young. I'm not a fan of Young, and my politics are very different than his, but I certainly won't lay blame at his feet for being too right-wing or supporting wars, as this was never the case.
