"Well, a dispassionate look at the evidence shows that the human species has moved away from reliance on pure BF as fast as it can over all the millenia."
Sorry - what on earth are you talking about?
Babies have LONG been given solid foods in addition to their mother's milk. Sometime earlier and sometimes later than is given to them.
But in evolutionary terms the almost wholesale switch to
"This is the killer fact, that the majority of mothers in the West do not use EBF, or even much BF, and their children and childrens children grow up perfectly OK - in rude health for the most part, in fact."
Well tell Andrew Lansley that then he can go ahead happily and close down the rest of the NHS without a worry! 
You can't get a doctors appointment at my clinic unless you phone within 2 minutes of the switchboard opening and that's because it's over run with people - mothers and young children included, who have health problems.
And maybe stop using the word 'woo' as a description of everything about breastfeeding promotion - including the mass of expensive and complex research that current recommendations are based on? Because frankly it's annoying and silly.
"the whole BF woo hasn't taken off in the West."
I think take an overview of human history, the bit where ff is the normal way of feeding a baby only occupies a space as big as a hair's breadth. Actually probably less than that. Whether women choose to give their baby their milk or not, all women in the West still go through the beginnings of the process of lactation, and nationally 78% now leave hospital breastfeeding. So not a minority choice. I'll give you that there are class and racial differences in breastfeeding rates. But then working class children always tend to get the worst of everything in life in the UK: diet, education, housing, so no change there.
