Math "No, I'm not seeing it from a child prot. perspective"
So why did you say that you'd prefer a teacher who was a "professional with CP training" hear if one of your DCs wanted to discuss a sexual experience than someone else?
"I do see it as prurience and I am baffled by it. I see fear there too. Do parents have so little faith in the way they bring up their children that they think the minute they reach sexual maturity they are going to turn around and have sex?"
I never said all conservative parents expect this or even fear it, but no matter how strictly you bring a child up there is always a possibility they will have sex or do other things behind your back (drinking, using porn, cutting classes, vandalism, etc.- anything you have taught them is wrong.) So this is when the girl HAS done something and told the deputy principal who set herself up as "approachable" on these issues. When there is an actual disclosure, not just fear your DCs might be up to something you disapprove of.
I still can't conceive of how you would see wanting to find out if your children were living up to your standards is prurience... if you wanted to find out explicit detail then that would be creepy, but anyone in school who'd listen to that level of description in the first place seems unprofessional.
"How is it sophisticated, white (????), urban elite, liberal, Christian, or woman's morals or any combination of those adjectives..."
I was referring to the particular woman in charge of school sex ed policy, who also happens to be the child protection officer, in the example I mentioned. None of these are universal.
But "sophisticated... urban elite" is due to the fact that the more affluent and educated do not as frequently hold traditional values. They are generally more liberal in religious views if they have any at all. Most of them would prefer their dcs had a series of sexual relationships between mid/late teens and 30+ while going through high school/college/university and building their career then married at 30-something to a partner they'd already been living with for some time than bring someone home to meet them at 20 and propose without yet having gone further than a kiss ("You're way too young to commit, you haven't lived yet!" or similar). As few sexually functioning adults are going to abstain until 34 or thereabouts, there is little hope of those who see young adulthood as a time for footloose and fancy-free exploration, self-discovery, higher education and planning for a high end career being abstinent until marriage; this is exactly what metropolitan sophisticates would see it as unlike the cash-poor, deeply spiritual communities from deprived inner cities which send their children to the school in question. It's a disconnect between those who put spirituality first and so make sacrifices to follow the moral code and those who put worldly fulfilment first and do whatever gives them pleasure.
"White" as in the UK apart from Northern Ireland, those who hold to these sort of values are a minority: they are typically found either in white-dominated rural areas such as the West Country, north Wales and the Scottish Highlands and Islands or in inner cities and satellite towns where the population is mainly of first through third generation immigrants from Asia or Africa. The most active extremist Christian churches are nearly always in Black communities in every large city in the UK. The older fundamentalist establishments of Free Presbyterian, Bible Baptist, Gospel Standard Baptist, independent Bible Church, etc. set up by indigenous Brits centuries ago by those who thought the established Church of England to be heretically over-liberal are lucky see a small turnout of greying faces every Sunday. Unsurprisingly, the other faiths represented at the school were almost exclusively non-white though the odd Caucasian convert to Islam exists here.
"Christian" as opposed to Muslim/Sikh/Hindu/Adventist (quasi Christian). What I was getting at is between social class, ethnicity and religion the teacher has a very different profile to the parents so she may be imposing a mentality that differs dramatically from what they expect, abusing her authority as a senior staff member and the trust that parents implicitly place in her to do the job she is being paid through their taxes for.
