Actually there is a huge logic to Rastafari but like any complex subject it may appear incomprehensible to thosen who dont understand where the movement is coming from. Surely all religion is by nature absurd, if it wasnt it wouldnt be religion and for me this makes Rasta a genuine faith. By all means find some sourceable criticism and add it but saying the Rasta beliefs are beyond the pale wont wash eg in their belief that life is to be lived here on earth and not in some promised after life Rastas have shown themselves to be far more rational than other religions, and in His Majesty they have  chosen a man of high moral calibre to be God and King, much better than all those false prophet cult leaders like Hubbard, Moon, etc,
