I suspect that his followers will not apologize for their own roles in this either. Instead they will play the victim without admitting their own responsibility for being gullible. As I have noted before, who is dumber -- the person promoting the fanciful deception, or the many who lap it up without the slightest critical thought?
In fact, I expect to see the opposite. Instead of admitting that this will make it harder for them to be as dogmatic and arrogantly certain of their own infallibility, I suspect that some of them will say that the experience "strengthened their faith". There's a prediction that actually has at least a snowball's chance in hell of being right.
