Query: John Gray has chutzpah, even if he doesn't have a PhD

Wow, this edition of "Dr." Gray's work was released even after his PhD has been debunked. And yet he still appears as "John Gray, PhD" on the cover of his book! He bought his PhD from a diploma mill. He's a fraud, a charlatan, a huckster.I'd like to think that after a man who rose to fame peddling himself as a relationship guru -- while using false credentials to bolster his claims -- would find himself humbled after his PhD was revealed to be a fraud. Apparently, John Gray lacks humility and basic human decency, as well as a PhD.What John Gray has is the ability to tell people what they want to hear. Maybe he should sell a diet & exercise book too, and tell us we can eat all the chocolate we want, and sit on our fat behinds while watching 7 hours of TV, followed by 5 hours in online chat rooms, and we'll get slim & trim by doing so!Sincerely,Madame Beige, PhD, B.S.A., XyZ, PdQ
