>The left in USA has been convinced (or convinced itself) that identity politics is more important than human rights.

I disagree. I think we had torture so that a President could look tough on National Security as a re-election strategy. Not-torturing people and "identity politics" are not mutually exclusive, there is no reason that we couldn't have both. "Identity politics" is fundamentally about human liberty and the dignity of the individual, a.k.a. individualism, which is also the same moral foundation that most arguments against torture rest on. Advancing the rights of the individual advances the case against torture.
