The devil, they say, is in the detail!!! aha... I'm not so sure myself. It's a very strange place for the Prince of Darkness to reside. Why hide there when you can walk abroad and wreak havoc in the world of general principles? You can spread plenty of paint with a broad brush and you can spread plenty of mischief with a broad-based assumption.

Can one really stir up quite as much trouble with some fiddly-widdly, petty, predicative factor?

I don't think it is the detail we need to look at...It is the big idea. Need to ask just one question, who does it benefit most?
