Well, dissenters make more interesting interlocutors than parrots. Given the choice of having as a dinner guest a dissenter or a party line mouthpiece, I'd go with the dissenter.
I've never found catholic dissenters interesting conversationalists. It's just Liberal mental illness applied to theology-once you understand the gist of their mentality-human beings are random proteins, we are the ultimate creators, and all human happiness is what can grab in this life–then you can complete their argument and sentences before they can. And having once owned a couple of double yellow-head Amazons, I would definitely pick the latter for companionship.
Gosh. I'd love to listen to some of the non-dissenters.
A non-dissenting researcher might have even more stimulating discussions, since "adult" stem cell research is yielding the goodies.
