I met a 40-ish lady who is into some New Age stuff. We talked about religion and it turns out she comes from a strict Southern Baptist family AND is an Ordained Preacher therein.
I didn't press the issue (wanting to be polite) but I did mention "Supermarket Spirituality" - as her Hindu dances, channeling, and more private stuff is way off the map for a fundie. She didn't seem bothered by this as she reasoned that 'Jesus is still Lord somehow and God is still the Creator somehow". I gave up with logic after that.
Anyhow, this pick and choose attitude about religion is two edged. Sure, you can erode traditional religion -and the 'truth' with it, but the people involved may be defiantly irrational about it and still support repressive religious organizations, anyway.
I suppose you could argue that outcomes would be different if the rest of the family wasn't applying peer pressure. I also think in the case of the Watchtower, the effect of these incompatible practices could push people away from donating and real meaningful support of this cult. More Witness fake-attude.
So, bring on the Yoga and whack-a-do healing and thinly disguised shamanism. Eventually, it helps....
