He's against same-sex marriage.
You're assuming that there was an option which was
for same-sex marriage here.
He's been accused by many of collaborating with illegal actions and human right abuses during the last dictatorship.
Without proof, presumably. Since, you know, he's not been arrested or fired. (And the next Hitler's Pope reference gets somebody beaten because what the hell was the Church supposed to do about Hitler anyways? Denouncing him just gets everybody shot, you work on the down low or you you don't work at all.)
He's a very influential political figure against the current Argentine administration (and I like my state as separated from the church as possible).
That strikes me as a good thing since very few people outside the country are fond of your current administration, so what's bad for you is good for the rest of us I guess.
He's also the guy who refused the perks of being Archbishop and rode the bus, and has a reputation for being against creature comforts of rank and believes in the mission of the Church to do all the sorts of things like feed the hungry and house the homeless and justice for all that have been kind of neglected in the arguments over gay marriage and Vatican Two and stuff like that.
