You're confusing what some filthy jew said about Baptism for something that I did not say about Baptism. Perhaps we should have warning labels for revealing the things that jews believe about our faith.
The point is to show normies what jews think of our Baptism. Their opinion of it is not far off than their opinion of our Lord. The presence of Marranos and Conversos is a historical truth that some part of their soul is either unwilling or unable to receive the full blessings of Baptism, as they are forever wired to destroy Christendom. They will always struggle with what they are, and they have no one to blame but themselves.
His blood is on their hands forever, so go figure they cannot find peace in the most beautiful of sacraments but only disdain.
