It's the refusal to examine what may portray 'your group' in a negative light that is the issue though, isn't it Egosum?
'It's negative therefore it cannot be true' is illogical, nonsensical.
Though TBH it is approaching the 'have faith' rationale. No proof of existence of divine supreme being = have faith.
Person questions whether the rules of a religious group may inadvertently be causing harm as well as good? We just have to 'have faith' that they don't. 
There has been no othering, no insulting, no isolating from me. I have presented facts and asked for evidence and research. I have also questioned the reluctance of many to accept the hypothesis or the dismissal of the idea out of hand.
