"I would explain that no, it isn't fair, but then many things in life are not."
And would you explain why we should tolerate and perpetuate this unfairness when there is an easy way to address it: by stopping church schools from discriminating against local children from secular families?
"There is no fair way in school admissions. If you banned faith schools, there would still be oversubscribed schools with an admissions criteria which people would question if they could not get their child into it."
Sorry - this is nonsense. Parents question admissions policies which are unfair and discriminatory and they are right to do so.
Where selection is considered unfair in the UK it's generally on the grounds of socially selective catchment areas (house price discrimination) and religious discrimination. Ways round this are to introduce a lottery system, which is becoming increasingly popular, and by having a system of fair banding, so that children from all abilities and social backgrounds across a reasonably wide catchment area can attend an oversubscribed school.
"If you say that every service funded by taxpayers had to be fair, then great, let's also stop the postcode lottery in the NHS, make all hospitals offer the same service to everybody. But the question is money- how do you fund it?"
What about hospitals refusing to treat local people if their parents weren't church goers? That's actually a bit closer to the situation we currently have with church schools. A primarily public funded institution refusing to provide a public service to local people on the basis that their parents don't attend church.
"It maybe does not seem fair- but lots of things are not fair- campaign against it if you like, but I can't see faith schools being banned because of that."
What - we should just accept unfairness towards children because lots of things are unfair? And because it's difficult to change?
