I've got no problem with old songs of poaching, whaling etc. BUT any racism, sexual violence, or homophobia I will not sing, sing along with or tolerate in any context. Murder Ballads - for sure, but it's the insidious nature of racism and homophobia in folk that particularly that annoy me, likewise the anti-PC line. And still you get random Morris Dancers backening their faces in the name of some non-existent Tradition, as if that's any excuse.
