Lambeth schools as a whole outstrip the national average for achievement, even before you factor in the various social factors. Lambeth is in the top 10% of areas in which your child is most likely to attend an ofsted 'Outstanding' school.
There is, I think, an overall shortage of places in Lambeth, but there is a new secondary opening on the S Circular, and my guess is that this will have quite a wide catchment as it is within what is already the catchment for 3 other secondaries (Elmgreen, St Martin's, Dunraven) possibly 4 (I'm not sure how far the Evelyn Grace catchment stretches), and an area where some parents choose Kingsdale, Graveney or the Sutton grammars if they get a place.
If there is an overall shortage of places, I just can't, in principle, support any new school that restricts access to any sector of the community. (I see that if designated by the Diosese they will offer 50% of places on 'non catholic' criteria, and if not designated they will not include faith as a criteria) but I think scaremongering about creationism is a bit much. His book seems to do what many other people (with lazy intellect, IMO) have done, lay mass violence by horrible people and groups of people at the door of religion, where he lays it at the door of people using 'social darwinism' to try and justify their will to opress, denigrate and conquer. There is nothing which suggests that he rejects the Darwinian basis of evolutionary theory.
As an atheist I am as disgusted by people who have used Darwin's 'natural selection' principle to try and excuse eugenics, racism, genocide as I am by sectarian violence, The Crusades, etc etc!
