My ds now goes to Beavers, despite the republican, atheist inclincations of his parents. The point was, he wanted to go as his friends go - and we weren't going to stop him becasue of our principles
He gets more "religious" indoctirniation at school, where his (non-denominational) school covers all the religions. I have more difficulty counering his questions about Jeus and God which arise as a result of school discussions than enaything that has ever come up at Beavers. Until we go through with proper disestablishmentarianism - removing all religion from schooling, then that will continue to be the caee. As far as ds is concerened, Beavers are a chance to run around, play games and have fun - not about the Queen or God.
In terms of helpers, both helpers for the Beavers are women. The Scout leader is a an old guy - who is greatly respected. My dh helps out occasionally - as do the parents of the other kids (mums and dads).
My SIL is also a leader at a different pack. She is now engaged to her ds' Scout Leader - cos he is such a nice guy!
There may be the odd pervert involved in the Scout Movement - as there potentially in any hobby. I can't comment, as I have never come acorss any - not am I aware of anyone else who has. But I am not going to stop ds from doing things that he enjoys just 'cos of that miniscule risk. (As MrMariella points out - the odds of abuse are higher in the home). The repsonsbiity is on us as the adults to be alert to anything that our instincts say is wrong - and also to ensure that our children are confdent enought to rasie any concerens that they may have.
CRB checking is only as good as the moment it is applied for. It is no substitute for sensible vigilence. BTW - it is not an offence to make use of people who have not been CRB checked - only to have taken on people who are on the Sex Offender's Register - subtle difference.
