Oh, and whilst I'm here..
Religious teachers who try to crush any notion of free thinking within my school.
Examples are as follows;
- Sex education: When showing the mandatory powerpoint presentation on contraception, we are helpfully provided with the failure rates of the contraceptives just in case we
think that sex might be a good idea. Condoms are given a failure rate of '0-20%'

that's the only one I remember, but other ones had similar failure rates..
- Before showing a video of Tony Robinson (I think that's his name..Baldrick) speaking on behalf of Terry Pratchett on euthanasia, he says 'now make notes on what he says, and note the many flaws in his argument'.
- Refusing to accept that religion has been the cause of any conflict
And so on. It's a Catholic school, if you hadn't guessed.
