I think you are misinformed, Jen.
The philosophy and ethics courses have been offered since I did my GCSEs in the very late 80s/ early 1990s. I remember friends studying responses to abortion back then. Certainly, it has existed ever since I've been a RE teacher (1997). So the philosophy and ethics course has been going a good 20 years or so. Hardly a recent development.
Unless you are at a school of a religious nature, then RE has got to be non denominational. That means they cannot tell children 'we believe that Jesus...'. It's all about learning what other people believe and exploring whether those beliefs have any value for us (the A02 side of the course). However, most importantly it teaches children to question and to think.
When I taught this subject at secondary, students often used to say that it was their favourite subject because in RS there are no right answers, it is all down to the quality of the debate / argument put forward. Students really like that, for once they're not told what the right answer is, and they have to think and decide for themselves. I remember holding debates and discussions over whether ghosts were real in a year 8 class. Whilst the children didn't necessarily change their minds on what they thought about ghosts, they sure got one hell of a lot of out thinking about what constitutes proof / evidence, whether other people's testimony is enough to believe something, and if so under what conditions. Etc etc...
And that's before I start talking about having children from different cultures sharing their beliefs and values with each other, and learning about each other's religion, and learning to get on.
RS is such a valuable subject in a multi cultural society, that it makes me sad to see people write it off, before they even know what it involves. Done well, it is an excellent subject and one my students have often valued. It always seem to be the parents that have a problem with it!
