My point being more that it's the randomness of the fervour/interpretative creativity of the evangelist in question. The ACCESS Ministries program that is delivered in schools is still delivered by volunteers who are known to add their own bits and stray from the program. It would be difficult to keep track of how it's going here from the UK, but there have been many breaches - the latest one where kids in one Victorian school were given a booklet on how girls make boys think and do bad things by the way they dress, in place of the standard bible they usually give out. Since that incident was publicised ACCESS released a statement of how their program is educationally sound and uses curriculum, which was quite a load of made up bollocks in itself and many schools retracted the notice after it was published in newsletters.
The thing is, allowing such privileged access of Christianity in our public schools seems like a great idea to many Christians, but really it undermines the freedom of ALL religions to be free from religion in schools. There are, in fact, many Christian parents who support FIRIS' work and don't agree with the SRI program. If you think about it hard enough you'll start to see the implications for everyone's freedoms. The arguments used by ACCESS and many right-wing Christians lack all credibility (invoking the idea that kids can't understand history and literature without being indoctrinated into Christianity...pfft). Christianity is not the cultural zero, and kids don't need to be taught it in order to appreciate that people around them might have beliefs that don't fit in with theirs.
There are 'little known sides' to all religions, in fact, and aspects of various religions can be taught in social science or history classes, not by unqualified volunteers who undermine the rest of the curriculum.
That's all an aside to the OP, but relevant, too.
Meanwhile, I came from that dual background and was very hurt by it - imagine the confusion in a child who is told their parents are going to hell for not even being Christians. It happens, I have friends who have had this come into their home after SRI lessons.
