I find right-wing songs offensive, I find right-on songs (usually) embarrassing. But traditional folk is a bit like religion- people take out of it what they bring into it. So I'll certainly put a leftish spin on songs that I do sing if I want, and expect others to do the same. Sometimes people with politoics different from mine bring up valid points (in song or otherwise)- and that's to be addressed, and mulled over, and a better point made (in otherwise or song), I don't just call them a Cameron. But some people - people- Al Q, BNP, Scientologits, ETA et al- there's no arguing with them in any way, so I don't. And playing bluegrass, or Irish, or Swedish tunes, who's to know what you think?

Nigel as usual has the British left-ish view well put.
