One reason that I don't talk about the abuse crisis much on my blog (and there are plenty of Catholic blogs where it is the only thing they talk about) is that I don't think much is gained by blogging endlessly about it.
Your idea that the instances of abuse arise from something systemic in the Church is not original. As you point out, there are many who share this idea - including members, priests and some bishops in the Catholic Church.
I usually find, however, that those who argue in this way have some other agenda in play. The argument goes like this:
There is disproportionately high instance of abuse in the Catholic Church,
therefore there must be something in the Catholic system which is the cause of this abuse,
I identify X as the cause (completely incidentally, I happen not to like X and have always wished that the Catholic Church would do away with it) therefore I cite the abuse crisis as the result of X and call upon those in authority in the Catholic Church to do away with X.
Now, X could be anything from the celibacy of priests (eg. Paul Collins), to the all male priesthood, to the priesthood itself (Gary Wills is a good case in point here) - or the Pope, or the Bishops, or indeed the Church itself.
I am sick of commentators using the abuse crisis as their opportunity to push their own particular agendas on the Church.
In this way, the real crisis goes unaddressed and a whole lot of pet causes get more airing than they should.
In the mean time, there is very little that I can do about it. Stupidly, perhaps naively, I actually trust that the Church herself, precisely through the systems of authority that exist in the Church (properly exercised) still remains the best means for eradicating this evil. This is why the crisis is a very central part of the conversation currently taking place among the Cardinals in their general congregation at the moment.
In the mean time, the fact that the governance of the church is none of my affair, I remain happily free to continue to take great joy in belonging to the Church, and sharing that joy with all who will receive it.

I reply (revised and expanded from my original):Now, as to your complaint that commenters on the Catholic sexual abuse crisis use the crisis to push their own agendas: I've no doubt that is the case. But that doesn't mean they are being disingenuous or that their arguments don't have merit. You are not doing them justice by maintaining this line - deal, if you can, with their arguments but best leave their motives to their own conscience.
I would never say you are stupid, David, but yes, I think you are naive to rely on the Roman hierarchy - as presently constituted - to address the crisis. The Cardinal O'Brien affair reveals why. If the reports are credible, and I believe they are given the Vatican's own refusal to deny them, the Vatican sat on a complaint against the Cardinal for 5 months and apparently sent a cardinal (Mark Oullett, considered by informed commentators to be a front-runner for the papacy) to negotiate a confidential settlement which would have enabled Cardinal O'Brien to retire "honourably" without the complaint going public. When the 'whispers in the loggia' reached the ears of other alleged victims of the cardinal, they promptly did go public and the whole sordid affair was exposed. When will Rome learn? As I suggested in my previous post, it is impossible, given that this affair concerned a cardinal, that Pope Benedict was not aware of all this. What was he thinking?*
I don't believe the inability of the Vatican to deal effectively with the crisis is just due to ethical obtuseness or rank moral corruption (i.e., that so many in the Curia may, directly or indirectly, be implicated in similar offences that they cannot afford to clean house without the whole house falling down), as some commentators argue, but that there is also a very significant theological dimension to the crisis, as I have noted in a previous post. Lutherans, as you might remember, have a habit of looking for the doctrinal angle in any issue; for us doctrine and life are as inter-related as marrow and bone.

"There is a kind of opinion that is an easy way of ridding (society) of the issue of pedophilia by putting it on the Church," Andre Vingt-Trois, the archbishop of Paris, told AFP in an interview.
"We shouldn't be duped. It's easy because that prevents asking the question within society itself," said Vingt-Trois, 70, one of the 115 cardinals set to elect the next pope in a conclave starting tomorrow."
Pot...Kettle...Black!
The liberals play dirty. The allegations against Cardinal Pell, who I believe is a man of integrity, were found to be not proven by a retired Victorian supreme court judge engaged by the church to investigate (Pell stood down for the duration of the inquiry - a good example, btw, of how the church should handle such allegations). The cardinal's own management of the crisis in his former diocese, however, has drawn criticism.
