I listened to JOB's show and I didn't take from it what you did. He was asking callers to describe what being a Catholic means to them, which I found insightful.
None of the callers had been abused by anyone in the Chuch although one caller did chastise him for what they described as glossing over the abuse of Catholic priests which he responded to quite respectfully, acknowledging the abuse issue but saying he'd covered that often on previous programme but that day was focusing on people's personal relationship with Catholicism, obviously because Pope Francis had only just died 24 hours ago.
I don't know all the details of JOBs background, but he has often spoken about his time at Ampleforth, which latterly was central to the abuse scandal (along with St Benedict's Ealing), I don't think he was abused though (maybe I'm wrong?)
it sounds like you find his delivery on air to be highly offensive, but then again the abuse scandal is indefensible and it is bound to ignite very high emotions. JOB is walking in a minefield every time he discusses it. He is probably one of the best placed people on air (along with Sheila Foggerty) to cover the subject, in terms of experience of growing up a Catholic.
I personally don't object to his discussion style (he used to grate but I think I've just got used to his devils advice style - he certainly provokes discussion which is what Talk Radio is there for), but he isn't everyone's cup of tea. My experience of Catholicism is not unlike Sheila Foggerty's (benign and positive from an educational perspective) so I was a lucky one, I guess.
