I do know (and have been happily employed by) clergy who I like and who I believe to be honest and sincere, though delusional. I don't deny their existence.

I could prove to you with many examples of religious leaders I know who know what they are saying is false and deliver it with the intent to deceive. Apparently you have had the good fortune to avoid these charlatans. I haven't. You don't strike me as the sort who would deny the existence of snake-oil salesmen entirely.

I won't hold them guiltless. But I forgive you for doing so.
