It’s not an ad hominem attack.
It describes his actions. He is focusing on the ugliest symptom: abuse of minors [and the latest addended victim group: “vulnerable adults”].
But he is closing his eyes to the deeper cause: a clergy that is wholly taken over by a network of homosexuals, some of whom who wish to change the doctrine of the Church, some of whom are willing to at least pay it lip service, some of whom enjoy an active homosexual lifestyle, some of whom at least try to be chaste. but all of whom enjoy the luxury, power, status, and easy life, and all of whom are scared to death that their evil network will be exposed. and their world will be destroyed in one big explosion of mutually-assured-destruction.
Walking off a short pier is an intellectual/non ad hominum response?
Only on FR does that pass for intelligent discourse.
I will ask others who actually read the Catholic League blog what they think.
CM did a write up on him several years ago. As you mention, he seems to have a history.
