It’s been my experience that whenever a subject being researched is initially perceived in black & white terms, there seems to be a tendency to filter the sources. In such cases it doesn’t seem to matter all that much what sources one uses as “references.”
As the old saying goes: Get a second opinion… if you haven’t already made up your mind! ;-) Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
