However, they in this particular case they didn't mention a thing about religion and instead tried to cover it up with tired excuses.
If they had debated it on the basis of school values or principles, there would have been an uproar but you would have been correct, because the school has a right to enforce its own policies on the basis of values and beliefs.
My issue with the scenario is the ridiculous stuff that she is saying now, when, from personal experience I know none of this is true. To lie consistently about what is permitted at Year 12 formals, even, when I have a friend who was turned down many a time when she asked to bring a girl last year, annoys me immensely.
Anybody who is willing to believe it is crazy.
On Schnagl's side though, if you listen to Hannah on 3AW, she does sound very uncomfortable with the questions she is being asked, which indicates media blow-up which may have been taken out of her control and spin she had never intended.
At the crux, this issue basically revolves around deciding whether to piss off the parents of the school who may be more conservative in true 'high income' style (although I don't speak for my own parents, or any of my friends' parents here) or whether to piss off people who don't give her a lot of money. It has nothing to do with moral standards or any kind of religious code upheld by the school...they don't have as many strict standards as you might think, detention doesn't even exist at IGGS.
