You would expect folk music to be egalatarian in tone, given where it comes from. But it is often extremely bellicose, which you would also expect; and here it does tend to part company with song-writers in the folk revival, who tend to come mainly from the vaguely anti-war left. Woody Guthrie sang with perfect sincerity of Flying Fortresses and Uncle Sam, but he was more or less the last of the old school. Those who have followed in his footsteps (in terms of writing songs with guitars) tend to a quite different set of political values. The modern "folk-singer" has never been happy with the gung-ho songs (or the hunting songs, for that matter), however much they suited the "folk" a generation or two back.
