I fully agree with the aims of the Dan O'Donnel society. We need to get rid of bad priests but the way they're going about it is black mail and threatening to expose the baddies in the middle of Lent seems like a half assed sutnt.
If you've proof of behavior unbecoming of a priest expose it and be done with it but don't play games like this. Besides if a priest in this diocese suddenly leaves every one will know he's one of the guys the O'Donnel society was talking about so he might as well stay put and try to bluff his way through.
