Given that atheists on this forum are very cagey about saying what they actually believe but contradictorily want non religious world views taught in RE (indeed Gordon, for example has said he is just here to counter the religious) what is it about non religious world views that posters and predominantly atheist posters want to be taught in RE?
Fill your boots.
While you continue to call it RE then it seems somewhat difficult to have a broad and balanced curriculum. In my kid's school many study Philosophy and Ethics, which actually (to my view) remains too dominated by religion, but the name is clearly more balanced.
So in a more balanced subject I'd like to see firstly an understanding that there are people who are religious and those that are not, and that there are people who believe in god or gods and those that don't. Effectively to provide context that is relevant to the UK today and also the larger world.
From there there should be a focus on major moral philosophical approaches, both religious (understanding major religions) and non religious (e.g. humanism, non religious deontological approached - e.g. Kant, consequentialism including utilitarianism, virtue ethics etc). And perhaps the best way of addressing this is not through a dry analytical approach but through 'hard' moral issues case studies. So for example whether it can ever be correct to steal, obligations to future generations on the environment, abortion etc etc - you can think of loads of examples.
The key being for the students to understand and develop their own moral approaches, which will necessarily come from a starting point based on their own upbringing and culture. My experience of teaching ethics, albeit at postgraduate level, is that students typically have a rather sophisticated and 'hybrid' approach - i.e. very few align with a pure ideological moral philosophy, whether religious or non religious but rather combine different approaches in rather complex manners. Also few would ever describe themselves as humanist, although many adopt a very humanist approach, likewise consequentialist etc.
So there you go, that's what I'd do.
