Why should a song which on the face of it appears to be attacking racism, recognising the existence of racism, and pretty, be seen as offensive? Sentimental, true, racist, surely not.

What is pretty dodgy is to try to rewrite history as to pretend that our societies have not been degraded by the existence of racism. And continue to be in many ways.

It seems to me that "Stay in your own backyard" in this song carries essentially the same kind of irony as Big Bill Broonzy singing "If you're black, get back, get back, get back."
