i disagree. i read the paragraph a few times over and i can see where you can possibly see the that kind of tone in there, but it just isn't there. they're simply saying that he's not an expert in political affairs, so his opinion is about as valid as a dentist's or a professor's.
if they said "the good 'doctor' tomaselli" and put "doctor" in quotes, then i would agree with you and zin. however, they were simply explaining what kind of doctor he was, since they referenced different professions that hold the title "doctor".
