He's probably been refusing for 10 months before being chucked out
However I recommend nipping over to R&S and reading Andrew's post on this
http://www.theanswerb.../Question1180225.html
"To enable young people to grow into independent adults the Scout Method encourages young people to question what they have been taught. Scouts and Venture Scouts who question God's existence, their own spirituality or the structures and beliefs of any or all religions are simply searching for spiritual understanding. This notion of a search for enlightenment is compatible with belief in most of the world's faiths. It is unacceptable to refuse Membership, or question a young person's suitability to continue to participate fully in a Section, if they express doubts about the meaning of the Promise
I find that rather interesting.
I still think they kicked him out to stop everyone using it as an excuse not to take part in brainwashing - er - religious activitities they don't want to go to.
