(And, "with respect", IB, I have 4 technical certificates and a BA in humanities.)

Knowledge, or even being in the know, was never a matter of academic achievement, especially when it comes to those subjects in which one isn't qualified, nor yet would appear to have any clear understanding of whatsoever, and yet in which you still - bizarrely, absurdly & infuriatingly - persist. What have there is not knowledge, WAV - it is a heap of cantankerously misinformed bugbears made all the more distasteful by the racist sentiments upon which they are based.      

about all I do know on the Green Man is... on Wiki.

The Wiki page, as with a lot of Wiki pages, is, to be generous, a tad misleading. For a more thorough overview of the issues check out both of the Green Man threads on Mudcat, and you might like to read my own wee introduction to the subject (as published in Folk Leads) which is currently on-line (in PDF format) as The Devil in the Details.
