I feel like the last one. I think that being spiritual means you believe and have faith but don't follow the religions strictly. Meaning, Being Religous and right can cause political thinking because maybe religion talks about politics and since he is religious and right he will follow the politics that his/her religion teach. A black protestant may also be political because of the protestant reformation in Europe. Ther was a whole war/conflict between Catholics and protestants. It also influenced who would be a king or queen. It ruled politics.
The black protestants refers to the protestant church where the ministers are predominant to be black. This church is also identified to be strongly focused on a political thinking as a part of their religion.
