Thank you for answering my questions.  I have to think about this some, and I do understand that this list is probably 
not the forum to engage in a long discussion, but I do believe that we are all going to need to develop an 
understanding of various positions to make an intelligent decision.  I appreciate you helping me to do that.  

Best regards,

Steve Jacobson
