I'll begin by apologising for not having read through the thread - not usually like me, but for tonight I'm afraid I just want to pitch straight in.
A yes/no poll is frankly ridiculous, and my immediate response is a question: are you talking about teaching a religion, or about teaching primary aged children about the different religious (and non-religious - we always get forgotten!!) viewpoints which exist?
I fully support the latter, and am entirely wary of and skeptical about the former, particularly when it involves a segregated faith school. I have a broad range of ethnic, linguistic and religious backgrounds represented in some way in my class of 20-odd 6 year olds, and I firmly believe they are benefiting from mixing with each other in the company of adults who value them all as individuals and do not regard their views (or perhaps at the moment, their parents' views) as better or worse.
