I'd be very surprised if you didn't know the kind of post to which I'm referring, though.
And yes, I absolutely agree that the 11+ makes state provision unfair - but that's not the same as 'patchy provision' in the sense that some schools simply can't be arsed.
In terms of this - Be that because you are rich enough to pay, or you believe in X religion, or your DC passed an exam on a given day, or even, that you happen to live in a good catchment. - I don't get why you think it's all about 'patting yourself on the back' anyway - most people, as I say, send to the school near them whatever it is like, and I think actually that more people are 'lucky' than you'd think - not in terms of going to ofsted 'outstandings' but because, IMO, there are a lot of very dedicated and excellent teachers in state schools.
There seems to be a sense that you would only ever be pleased with your child's school if you'd faked religion, or lived in an amazing catchment or whatever, and it's simply not so. Therefore, I would say again - there are things about my daughter's comprehensive I'm less keen on, and things I'd change, but she goes there because that was our only option, as is the case for most people - notwithstanding the fact that I'm very much pro-state education, and the more so the longer she is there - but I also think it's only right to counter some of the more irritating of the myths about state ed when they come up, and to laud the schools', and the system's, better aspects.
