My son was 7 before I left. He wanted to join the scouts soon after we left, but I felt very wierd about it. I finally allowed him to join the Cub Scouts last year and it has been a great experience for him. (He is 10 1/2 now). We were always told we couldn't join because it was patriotic, not affiliated with religion. I din not discover the religious angle until after he joined, since each Pack is sponsored by a church.
However, the scouts encourage the boys to be active in any church that they belong to, and have varius badges for all different religions the boys can earn if they choose too, it isn't required. We opt out of the religion part, but it has never been an obstacle to my son being in the scouts.
Many of my witness friends and I would call the scouts 'paramilitary'. It really is a great organization to belong too. It teaches repect and responsiblity. Like any other group, though, if you don't have a good Den or Pack, or if your kid doesn't put effort into it he won't get a lot out of it.
It is a shame how much witness kids miss out on. The scouts is not for everyone, but it is a shame that the Witnesses condemn it before they actually do their own research into it. Yeah, you really cannot be a scout without saluting the flag, but it is too bad Witnesses many times really don't know what the scouts are all about.
