Do we want any of this hanging over us, or is a clean break the solution?
It's all about how you percieve it. Ignore it I'd say, and keep away from the people that feed you all the JW nonsense about witch hunts/dirt digging etc. it's now got nowt to do with you. Or rather it has much to do with you as you want. Might mean being coolish with your parents but the alternative is probably no contact at all.
I'm not suggesting that the Alpha concept is a cult, just that you're not hasty. I've had 2 friends (nonJW) join then leave because of pressure to conform, but that was a couple of years ago and the group you attend might be quite different.
"normal human behaviour" includes JW behaviour in my experience. "normal" runs the gamut of human behaviour.
