On Wednesday Radio 4 aired a programme called White Mischief,which promised to trace ‘where whiteness came from and how its power has remained elusive.’ It asked whether white privilege existed. Or rather it pretended to ask. It assumed that it does. Instead of directly admitting that it was putting forward one point of view, it was one of those annoying programmes that affects a sort of light-hearted neutrality, and vaguely claims to be moving away from the unhelpfully limited conversations we have been having so far.
