Barack Obama's former pastor is in the news again, making three public appearances since Friday.

Even with all of his comments, it's nice to have some background information on black liberation theology, the discipline in which Wright was educated.

I did a Q&A with James Cone of New York City's Union Theological Seminary, and he touched on some topics that shed light on the issues that concern Wright and Obama -- like how the black community in America is, inevitably, angry.

Read the Q&A for more enlightening background. Talking to him really helped inform my perspective on these complicated issues.
