I could be mistaken, but I don't think Neil Young ever came out in support of the wars. He spoke out plenty against the Iraq war, including the song "Living With War".
He clearly supported the administration. I replied to another comment in this thread with sourced quotes.
The vast majority of Americans were of the same mind as Neil, and they all eventually turned against the administration when it was clear what was going on.
People are too quick to flag comments.
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.
