Why do you equate people who ask uncomfortable questions about the financial probity of an Educational Charity, EV(UK) , with studies done on 'apostates' from fringe Christian movements ( your selections in the thread below).
Perhaps you could clarify whether or not EV(UK) is a genuine Educational Charity, or just a front for believers in a wacky new age religion. If the latter, then I'd suggest you put it to Prem, the next time you have an opportunity to speak to him, that you'd all be better off & would draw much less heat, if you privatised the whole operation.
If the former............prove it.
