When everyone else is reporting that the Vatican confirmed the meeting, you're going to rely on Think Progress to be the lone reporter of the truth?
No, that was the only story I'd seen on it. Still, looking at other media outlets the truth appears to be that the Vatican has refused to deny that the meeting happened, not that they confirmed it. It's not the same thing, although I won't argue that it may in the end amount to the same thing.
And if it does turn out that the Pope met with her, do you think that it's going to somehow shatter my hitherto unshakeable belief in the purity of the Catholic Church's vision? The current Pope is doing and saying a whole bunch of things that are good for society as a whole and by extension the organisation that he represents, especially relative to his predecessors, but let's not pretend that he isn't also in favour of a whole load of anachronistic bullshit that's designed to keep women barefoot and pregnant and the Catholic Church rolling in the cash. This isn't a binary situation.
