So he turned to Islam? You obviously don't know your history about Muslims. They sides with Hitler in his genocide. And, Muslims still continue to preach fascism.
I had no problem with Ali fighting bigotry. But, calling all white people devils? Maybe the Democrats who were supporters of the KKK. But, in 1974, much of the bigotry like serving blacks in restaurants had stopped.
But, now the devil is putting hate back into the hearts of blacks and whites. The process is through liberalism and progressivism. The attempt by man, through man, to perfect human beings, which cannot be done by man alone. Gullible people listen to the secular smooth messages and not understanding progressivism is the new Tower of Babel.
