No Jaracz wasn't a sex abuser. Pompous, arrogant dick = yes. Thought he was better than everyone = yes. Absolutely drunk with power = yes. But the man was practically asexual. Incredibly intelligent. Like Nobel-prize winning academia intelligent. But he must have skipped the chapters in the gospels where Jesus talks about humility. As far as his leaving or being removed from the Australian branch. The most likely explanation is that he clashed hard with other brothers at the executive level of that branch and was "voted out". The truth of what happened there seems far more uneventful than people like to accept.
