The question asked was tempered with Raptor's "not really needing any more spirituality" and his innate concern about "preachy people" who might not leave him alone. That said, it looks like the information offered here has been level-headed regarding concerns about some aspects of that particular church. I am confident that he'll figure out their motives and respond accordingly.
My best friend in high school had a horribly complex family life, with parents who married and divorced with a frequency that would embarrass the Gabor sisters, and who littered the countryside with half- and step- and ex-step-brothers and sisters. You needed a score card to keep up, and in the end, she became a hard-core Jehovah's Witness. It drove our friendship apart immediately and there has been no way to get past her religion to reclaim it. That church caught up with her at a time when she needed a major crutch, and my friendship alone wasn't enough to sustain her. We finally had to agree to disagree. She stopped sending me propaganda but she also stopped trying to be my friend. It has always been my regret that she joined a church that insisted she choose her friends from within their fold. It struck me as a form of coercion practiced on someone unable to fight against it.
