I'm Sorry about your skepticism. You did not identify any specific criticism nor offer any specific rebuttal or alternative facts that you have personally discovered through your research. So you leave me twisting in the wind in total darkness, dwelling here in my ignorance unassisted. I, of course, did not set out to prove anything to anyone, but answered your inquiry as a courtesy which you are welcome to accept or reject. I hope you will post the results of your personal research for the benefit of the rest of us. I am always happy to share my small knowledge with others and I am always grateful when others reciprocate.
