One of the most frustrating things.
When you confront JW's about what they believe they will often deny it. Such as "if your child is disfellowshipped then you can't have contact with them ever again". The reply you get will be a denial of that along the lines of "well there are circumstances where we can have contact". Yet, they've all seen the videos from last years conventions where a mother wasn't to pick up the phone up her long term disfellowshipped daughter.
Other denials come in the shape of the blood issue, god slaughtering everyone at Armageddon, factual cases of covering over paedophilia & the mistakes of the governing body.
Why can't they just own what they are? Why can't they take pride in what they're supposed to be, thus watering down what the commandments are from Watchtower?
It says it all to me. They're actually embarrassed by their own beliefs, so much so that most will deny or water them down.
