You dodged my question. I didn't ask about Bishop Williamson per se or about defrocking a bishop who had been previously ordained. 

So let me ask again, more plainly this time. If it were known that a candidate for the episcopacy held the belief that the Holocaust never happened, in your opinion should that preclude him from being ordained a bishop?

Just so you know where I stand, I think such a belief would, at the very least,  indicate an unhealthy and obstinate refusal to acknowledge historical fact. At worst, it could also be a warning sign of dangerous bigotry that is certainly unfitting for a member of the Catholic hierarchy.

It isn't just a matter of being entitled to odd beliefs. It's a matter of whether or not we choose excellent bishops. Being orthodox but delusional does not make for excellence. 

So, yes, I believe such a belief should preclude somebody from being ordained a bishop. Now please tell us, plainly, what you think.
