Rabbit Apologies - I wasn't trying to make it personal, but more general, where you had given a good example. Sorry.
icecream - you mention both "legitimacy" and "morals". I think the current situation is that it is legitimate to have faith schools, but that it merely a case of law and acceptance. I don't think it is morally acceptable for tax consumers (faith schools) to exclude other tax payers (e.g. people of the wrong faith).
However, straying some way off topic here as the thread is about covert middle class selection at faith schools.
My kids are at a faith school (yes - confessed massive hypocrite) and there is a very wide range of family backgrounds there - including, alledgedly, drug users, kids who bounce from one house to the next each night along with plenty of normal kids from modest backgrounds (council tenants, benefits parents, check-out staff, low income etc).
In fact, I'd say the "aspirational" and "middle class" types are far in the minority at this central London, outstanding rated primary school.
I do think that my kids have benefited from tax payers money whilst excluding kids who live closer to the school who happen not to attend the right church and believe in the right god. It's not morally acceptable, but we do it anyway.
