Thank you for such positive comments.
No, sofaqueen I'm not, or not as bluntly as that, and am not sure how many think mc parents offer advantages because 'pushy' or for many other reasons.
Most teachers I have seen recognise that good education is a partnership-that parents will know things about their pupils they might not, and that being willing to explain to parents why and how something is done produces better outcomes all round. And most teachers can justify decisions, and are willing to do so, since they are educators in the broadest sense. And obviously that's easier if parents are concerned with education and questioning about it.
But it doesn't work if it isn't reciprocated-if the parent isn't interested in the expertise or knowledge of the teacher, or the curriculum as a whole, or a range of aims for their child's development, and is basically 'pushing' for something to be done that might be disadvantageous. And I see it at the moment in a child who has been given flashcards to read from 18 months, yet can't work unless constantly badgered and has no sign of intellectual curiosity, and whose parents just will not listen to the teacher. And it's beating the real academic drive out of what may be a talented child. 
And that's the problem that I find so often, a real confrontational lack of respect for teachers and other parents, a 'pushiness' that is not about questioning but about telling.
I have no idea how free schools and curriculum reforms will work, but there is something very frightening about the idea that the model is one where parents decide, not where all those concerned with children discuss and rationally arrive at outcomes, as if education were simply a matter of different choices, like buying a car, and all you have to do is empower consumers properly.
Blimey, that was long, threw away the 'nutshell' praise a bit quickly. Hope I've not replaced it with 'nutcase'.
