Can we use this as evidence that the evangelists are wrong?

I am sure that I am not alone in being annoyed at the use of former atheists turned religious as evidence for atheism being wrong. So, I won't claim that the convertion of the president of the Evangelical Theological Society into a Catholic is evidence that the Baptists are wrong.

It could be used as an example of how moronic this kind of argumentation is.

No matter if he is a Baptist or a Catholic, Francis Beckwith is an anti-choice, anti-science creep.
