That is an ad hominem.
They can claim anything to be true, no matter how ridiculous, as long as there is no one around to contradict them.
This too is an ad hominem.
If church people are to trust them them, they need to know who they trusted for their outrageous claim.
That wouldn't be trust. As St. Augustine says, "For my part, I should not believe the Gospel except as moved by the authority of the Catholic Church." We do not demand from the Apostles the time and date that Jesus told them the things they teach in His name. We believe and trust their testimony of Christ. And we believe and trust the testimony and authority of those in sacramental succession from them.
Scripture together with the absence of any credible evidence for Eusebius's and Jerome's claims are witnesses against them.
No place in Scripture is there anything that shows that Peter's Roman bishopric was not 25 years. And absence of additional evidence is not a witness against them; that's the fallacy of the argument from silence.

SOUNDS LIKE THE INSTITUTIONAL STANDARD IS:
"THEIR arguments from silence are evil and heretical and nonsense. While mine are orthodox, righteous and wonderful."
