I don't want to start any argument or anyone to get defensive but if you know your history the social movement of liberation theology started with the catholic church especially in Latin America in the late 60's and early 70's. The United council of churches joined (protestant) and walla, Jeremiah Wright is preaching the exact same thing. This has never changed, if you go to countries like the Philippines you will still see the same theology. It has just moved out of main stream America for expedience.
