I should also say I'm feeling really sorry for the course in the thread title that seems to be instilling academic rigour and turning out excellent performers (and the mealy mouthed can take the last term and stick it up their fundament) and is being chewed over to the tune of 380+ posts on a web site by people few of whom have a formal qualification in the subject they're discussing.

When I begin to feel sympathy for WAV - which I do at times - I remember you started this intentionally, knowing what the fallout would be or blinding yourself to the consequences. As I said above, if you can't or won't engage in the debate beyond a 'wouldn't it be nice if...' level or cutting and pasting rhetorical non sequiters, don't start the post in the first place.
