Welcome Spark, I too have found that people in meetings generally aren't shoving God down anyones throat but that reading the BB can be extremely off-putting as it is clearly talking about a Christian God.
NoelleR who posts here said she sees the bb not as a text book on how to do the steps but a book about how those people did the steps...I liked that.
I think the spirit of the program can be worked fine without a belief in God (it is a practical program anyway), it took me a while to get passed the references to "the creator" etc though.
