It's the only choice that some have when an ex- of their organization speaks up and exposes the organization for what it really is, RC or not.
They can't deny the truth of what is said by someone with experience, so discrediting them is the only tactic left.
I've seen it happen many a time on the LDS threads as those who have left the LDS organization expose the blatant lies the LDS teaches.
INDEED. QUITE SO.
