Kenan Malik in The Guardian:
“As identity consciousness has increased among liberals,” Lilla has observed, “political consciousness has decreased.” That is to look at the issue back to front. It is not so much that identity consciousness has diminished political consciousness, but rather that the diminishment of ideological politics has allowed the politics of identity to flourish. In the 1960s, the struggles for black rights and women’s rights and gay rights were closely linked to the wider project of social transformation. But as the labour movement lost influence and radical struggles faltered, from the 1980s on, so the relationship between the promotion of identity rights and broader social change frayed. Eventually, the promotion of identity became an end in itself. The universalism that once fuelled radical movements has largely evaporated.
