Peasant, at one moment you effectively imply that it would be best if we just don't sing any songs with any political implications. Then Don Firth comes up with a piece of vile Nazi crap, and you lament the kind of "evil censorship" that keeps something like that off the contemporary music stage.
And as for the utter nonsense about waiting to produce a song until a song from an opposing viewpoint has been written: That piece of Nazi crap was written before anyone ever heard of Pete Seeger, Si Kahn, or Utah Phillips.
If you don't have an underlying political agenda of your own, your thinking is simply muddled beyond belief. If you are trying to push a personal agenda covertly, you are unbelievably thick headed if you don't realize how transparent you are.
