I think it's fair to say that religions spawned from an explicit desire to negate a particular aspect of the Catholic Church indeed is devoid of that particular aspect. That doesn't mean that protestantism is entirely rational, it's still a religion; but it's by definition different from catholicism in those specific ways that led to the schism. For example, I friend of mine got kicked in the butt publicly as a child by a priest because she dared to say that the host "represents" the body of Christ (while, clearly, it literally is the body of Christ, not merely represents it)
