The source of Gish's PhD is not the reason for calling him a charlitan. I think that it has something to do with the fact that he has often used factual errors to support his arguments, been called on these factual errors, apologized for making these factual errors, and then repeated the same arguments complete with their factual errors. Cite your sources, please. Your charges are weighty against this man's character. Such charges should be supported by weighty evidence.
