Let’s scale this down a little bit.
If there was an old organization in your neighborhood – with branches in many neighborhoods - that had long been granted tax-free status, whose officials dressed up in elaborate costumes and performed weird, superstitious rituals and incantations, and that was discovered to have been producing and protecting pedophiles, probably for as long as it’s been in existence, what would sane people do about the situation?
Would sane people continue to donate to and support such an organization?
Would sane people politely request, plead, beg, hope and pray that the scoundrels and degenerates would voluntarily reform, repent, clean house – let alone disband – and still continue to comfort themselves with the “blessings” issued by the president of the organization while they waited for justice and rectification?
