I looked, because you asked, Annette.
There seems to be a breadth of opinion on the site, not just the radicals. You'd think they were all on an MRA site the way they argue amongst themselves.
I didn't see anything about plots to take over and go back to the middle ages, but if there is something there it must be hiding behind a lot of reasonable, albeit passionate folk.
I was never a great 'churchie' type myself (I am a nominal Catholic) and always found Irish Catholics a pretty wierd lot. I had friends sent into Northern Ireland to protect the Catholic minority there, and were promptly shot at by those same Catholics. Stupid, murderous bastards.
The Catholic Chruch has weathered several major storms this past century, some entirly in-house. The watering-down of the litergy at Vatican 2 was a disaster that fractured the Unity of Catholics. It has ceased to be One, Holy and Universal. Maybe it can be again one day. I had hoped that Cardinal Rottweiler would bring back the Tridentine Mass but all he has done is suggest it be used. I had hoped for a bit more bite. It is almost inevitable with human organisations that when the central core ceases to hold things together, all sorts of reactionary groups splinter off.
