@Berty McJock,
I don't buy the nazi youth thing - it was compulsory for all boys his age and there's nothing that suggests he was enthusiastic and his actions after suggest he was never sympathetic, though I understand you were making the 'wrongly or rightly' point. Besides I don't think being a 14 yo old in the Hitler Youth is anything compared to millennial sexual child abuse and pushing Benedict out of the picture isn't going to make a lick of difference to that stain. Nor is scapegoating him for any of the other institution's perceived failings (from sexual health to the place of women) they will remain post-Benedict.
What little I've read makes me think it's not the more progressive parts of the church pressuring Benedict because of his relatively conservative stances - in fact it seems the front runners as replacements are from the same camp and a couple have even studied under Benedict.
I wonder if being appointed pope is considered a good thing by the bishops (at a personal leverl), or a duty to be born.
A couple of comedians have drawn parallels between the Vatican and the GOP (conservative old white guys concerned with preserving influence) , worth a giggle I guess, but on a more philosophical level it has made me think how much an institution can change without risking it's position as an institution - Resistance to change is sort of the point of strong institutions, they don't bend with societal winds all that much, so when they change direction they are still there providing stability and consistency, for better or worse.
