Urban Northern blacks, it might work on. But rural Southern church-going blacks? I don’t think so.
It’s a question of being equally unfair to whites because whites have been unfair to blacks in the past. Or being fair to a fellow devout Christian who’s white, as one would have wanted whites to have been fair to blacks in the past. Or put simply, a question of ‘get whitey’ or ‘America living up to the true meaning of its creed’. Jones ought to fire his handlers. It’s a no-brainer, and easily turned around against him.
