This is the level of argument that I would expect from someone trying to defend someone like Stella Immanuel. Just because you are credentialed, this does not mean you are necessarily credible. If you do things that make you seem foolish on the stand or make self-contradicting and untrue statements (which he did, by the way, and needed to retract several statements after being questioned about their contradicting nature), your credentials mean nothing because people wont trust you.
