Well to be honest, it would be nice to see a valid certificate, or to see an accredited University confirm his doctorate. Do you have any idea how many creationists have PhDs? (of questionable origins mind you). But regardless, that's not the point. Personally, I'm not particularly irked if you refer to him as Dr. Rowbotham. The title of MD or PhD does not automatically make one right in my opinion. Lots of individuals with MDs and PhDs have been wrong about oh so much. For instance, sad as it may be, it is perfectly possible these days for someone (in the US especially) to get their MD with only a slight and frankly laughable understanding of evolutionary theory (the cornerstone of modern biology upon which medicine is founded.. a scary thought, both to myself and other doctors out there). But my point is this: I'm more concenred about peer review and consensus within the scientific community, than with one man's theories and explanations, especially when I can counter many of them myself. His titles mean nothing if his ideas don't stand up to scrutiny. But alas, if we are going to discuss particulars about the individual, let's not also forget that in addition to his degrees (which let's say he had) he was also a biblical literalist. Hmm...
