So the answer, as always, turns out in the end to be: "Because I can't help it." Or at least, "Because I don't think I can help it." Fine: but an admission of helplessness is no use to anyone. Luckily there are plenty of people who CAN help it available to expose this vile and corrupt institution, and their numbers are growing all the time.

Being a long-time troubled-listener to Geraldine Doogue on RN, I'm glad to read her thoughts and have an opportunity to base a comment on more than just fleeting impressions. Geraldine, along with many others at the ABC, is living proof that the ABC is far from the left-wing bastion it's often made out to be. Indeed it's absolutely institutional and rarely does a radical voice receive a earnest hearing.
But back to Geraldine, who's perhaps the ABC's institutional figurehead and superciliously oversees the radical voices that break like combers against her proud prow. One can often sense her disdain when those who dare to thumb their own noses at the institutional religion, politics, economics and ethics she supports. Sometimes she's quite explicit, intolerant and dismissive in her eloquent, plummy way, yet she offers no real argument against those free radicals she patently despises, only her magisterial displeasure, politely and jovially disguised. Sorry I have no instances at hand, but I've heard it time and again.
As for the article, I find my impressions born out. Geraldine has such a strong sense of vocation, as she says herself; indeed I'd call it self-importance; the way she holds forth and questions herself rhetorically--stagily--and talks of epiphanies. As if her insights are of great moment and she's compelled to share them, that we all might benefit. As if she's capable withing her institutional mindset of the radical humility Christ exampled and the Catholic Church has parodied ever since. She's not. Her faith holds. But faith in what?

This article seems to demonstrate that the old Catholic adage that: "If we get them early enough, they are ours forever!" holds true. Geraldine can't escape her indoctrination no matter what.

It proves that exposing small children to religious indoctrination is equivalent to child abuse!

…The Catholic Church is marked by radicalism from the start: Maybe now is the time for the church to deconstruct its “formalisms”, and join the world which Geraldine Doogue has acknowledged, (as a practising Catholic), actually exists.

…The Catholic Church has proved its success in crushing dissent, since before the times of the “Arians”; "will anything change"?, Geraldine reluctantly asks

David G's response of typical of the current wave of irrational religious paranoia sweeping the community. Christian religions contain some very worthwhile lessons and have been one of the bases of Western progress in the last 200yrs. Its wise not to confuse christian principles with the problems of institutional churches. That's like dismissing Science because there are corrupt scientists.

The Catholic Church and others sets Christ up as a scapegoat and then appoint another human to grant redemption. The late Christopher Hitchens summed up the faults of such a system better then I can.

He wrote;
I find something repulsive in the idea of vicarious redemption.
I would not throw my numberless sins on to a scapegoat and expect them to pass from me; we rightly sneer at the barbaric societies that practice this unpleasantness in its literal form. There is no value in the vicarious gesture anyway.

As Thomas Paine pointed out, you may if you wish take on a debt, or even offer to take the debtor’s place in prison. That would be self-sacrificing. But you may not a assume his actual crimes as if they were your own; for one thing you didn't commit them and might have died rather than do so; for another this impossible action would rob him of individual responsibility.

The whole apparatus of absolution and forgiveness strikes me as positively immoral, while the concept of revealed truth degrades the whole concept of free intelligence by purportedly relieving us of the hard task of working out ethical principles for ourselves.
Christopher Hitchens - Letters to a Young Contrarian –Ch. 9 P5

Geraldine appears to be making progress on that hard task.
