I've always felt that her beliefs were truly felt and without animus, sort of like Dorothy Day. Unlike a lot of lefty performers, I can still enjoy her music without feeling either guilt or anger.
I mentioned that Baez was performing and my son said he was surprised. He thought she had spoken out against the actions of the North after the war and had come to realize the US wasn't the only problem over there. I didn't know this about her. It does seem to jibe with what you posted.
I guess it's possible to be against all war, but what I don't understand is the inability to see the bigger picture behind beligerent actions. Why do these protesters not see that freeing women from the Taliban in Afganistan or making it so Iraq doesn't have thousands of innocents in jail anymore is a worthy endeavor? That's the part I don't get. The protestors have all the freedom in the world yet seem unwilling to let others, who might have to gain freedom at the point of a sword, have theirs.
