My inquiry is friendly in a 'civility' sense. I am not personally challenging you, rather I am challenging you as a co-editor and collaborator.  That is what I meant when I wrote: 'I challenge you to do this per WP:V'. WP:V "...in a nutshell: Material challenged or likely to be challenged, and all quotations, must be attributed to a reliable, published source."

Please do not perceive my challenge as personally threatening, it not intended so.  Civil order at Wikipeidia exists between editors with different points of view, in large part, because we all agree to follow WP:POL.  Could you therefore please answer my questions?  Thanks.
