I don't object to political songs per se, and in fact there are some that I have regard highly. I think a song like "Lyndon Johnson Told the Nation" by Tom Paxton makes a very compelling point, in a way that perhaps could not have been made as well in another medium. But I've heard a lot more bad ones than good ones. Some topical songs are quite enlightening, but a lot of them are obvious propaganda in a pretty package. And I see no reason why I should credit a lame message more because it's conveyed in music.[I don't know "Stand Up For Judas," and am neither an Christian nor an anti-Christian, so I can't really comment on that one.]
As for the relative knowledge of "activists," I have a good deal of experience with this, as I have worked in the environmental protection field since the 1970's (in both the public and private sectors). I find that a lot of activists are NOT particularly well-informed on the issues, and are not all that interested in exploring them in a balanced, objective way. I think that a lot of people become "advocates" when they should still be in the learning stage -- and after they make the shift from student to teacher, they use most of their brain power to support, defend and advance their positions, rather than to reexamine them.
Anyway, the question Roger asked was whether "most Mudcatters are like [his] friend and are not too happy with the political songs that portray recent events." Speaking only for myself, of course, I think Roger's friend and I have a lot in common.
