I agree. So let the anti-Christian left provide all the verifiable, credible evidence they have to prove this "story." Unless they can, then they are guilty of slander, and they deserve to be beaten back hard by the Vatican.
We can't simply presume that someone is guilty of something when the accuser won't provide credible, verifiable evidence of any wrongdoing and the party being accused won't mount a defense as a result.
It is unknown except to God and a few people whether the accusations are slander.
