With every thing that seems to be developing throughout this specific area, all your perspectives are fairly stimulating. Nonetheless, I appologize, but I do not give credence to your whole theory, all be it stimulating none the less. It appears to everybody that your comments are actually not completely validated and in fact you are yourself not completely convinced of the argument. In any case I did take pleasure in reading it.
