"...are you telling me that we shouldn't disfellowship pedophiles...?"
Yes, they should. More often than not, they don't. Thanks to the two witness rule. Which was implemented to protect the reputation of the WT at all costs, including the cost to actual justice. That's some pretty cultic behaviour, right there.
"I consider it completely just that a pedophile is removed from the congregation."
As would we all, should it happen, which it often doesn't, and the victim is expected to continue to attend with their abuser. That's some twisted cultic logic right there. And true justice involves actually calling the police; you know: the actual justice system! Not involving the secular authorities to protect the religion's reputation is again pretty cultic.
