A "pro-gay" pope? I don't think so. Not in my lifetime, anyway.
Tony Blair is a recent convert to Romanism. Therefore, it might take him a while to realize that Rome doesn't have the same pragmatic, ethical categories favored by politicians.
So, Blair has noticed the liberal-minded attitude of many Catholics about homosexuality--and he's probably correct in his assessment. He then mistakenly assumes that this is a problem of church unity because the rank and file catholics are more open to gay unions than are church officials.

Blair naively seems to think that the problem is the "entrenched attitudes of church leaders" who (it is implied) will eventually moderate over time. But the infallible church you have now joined, Mr. Blair, doesn't get these things wrong. And those crusty, well-entrenched Cardinals are not particularly interested in what a former PM might think about anything.
Better get used to it, Mr. Blair. You'll be kissing the pope's ring. He sure won't be kissing yours.
