Well I think you're missing some nuances. First, politics wheedles its way into our lives in all sorts of ways and folk song is no exception. There's politics in songs about badly-done-to sailors, there's politics in songs about maidens badly treated, there's politics in Nobody Knows You When You're Down and Out. There's politics in Pretty Boy Floyd. There's politics in songs about whales, and, what's more, your "hard-line singer" might be my mouthpiece for social justice. There are two points to be made. First, it's how the point-making is put across. If it's in-yer-face preaching, bad, unless you're a compete acolyte. But if it's put subtly to get you thinking but not telling you what to think, well what's to object to? After all, we are all grown-ups. Second point: just don't go to the gig. Or go to the gig if the guy is that good, bite your lip and enjoy the other stuff. That was me with Vin. Objectionable apropos of abortion, two percent, the funniest and most joyously life-affirming man on the planet, ninety-eight percent.
