Agree. His mother was an atheist. He was raised an atheist.
Rev. Jeremiah Wright and Trinity United Church of Christ subscribed to black liberation theology (i.e., marxism) and he was at home there.
At the same time, I would contend that a.) he remains an atheist but b.) with distinct Muslim sympathies.
I think that Barry may think of himself as a Christian, but his “Christianity” is basically watered down to conform with his secular humanist views, and blended with racialist liberation theology.
