Did he have to give the stage over to some right-wing country singer like Toby Keith to balance his program? Of course not.

exactly!

but he would have been doing a better job and more worthy of his sainthood if he opened the floor that he alone almost, possessed to others.

This is what you do when you are confident of your position. Who cares let the audience decide if you are primarily interested in music. Seeger was primairly interested in using the power of music to support only one point of view. In this way he can not be separated from those who on the other side of issues who did the same. (german nationalism on and on)

And he was successful. The possibility of someone doing the same thing on a from the bad or dark side is scarry. But if Seeger did it -that makes it right...No....the power folk music was simply used without competition for political purposes. That is never right.

That makes his concerts political rallys hammering at one political view alone endlessly.

Yes he did other things and yes he fought for good causes. But the fact that he manipulated the interest via music on behalf of one point of view is not good. I am sure that If he had been more balanced more inclusive the people would have made the right decisions anyway. So why not diversify access to media and stages?
He could have done this. So not my problem his.
