Yes, but only with difficulty!
Lest one misconstue my comment, I would like to put it in the context of pointing out that the source for this article, CMRI, is comprised of sedevacantists actively seeking to divide the Church by trolling for membership directly from mainstream ranks. They are highly active in this vein here in the Archdiocese of Boston. They may mean well, I suppose, and they seem pleasant enough as individuals, but they are hardly improved over the Seattle cult they spun off from a few years back, and should be treated like a flying bullet - avoided at all costs!
I think at least, Pivarunas's criticisms are valid for debate among Catholics.
I know a lot of RadTrads, and yes, they are really bad as individuals. I dated an ex-SSPXer once upon a time, and she made the Puritans of Massachusetts seem like hedonists.
I still think criticism of Vatican II is legitemate. If I had to be stuck with a Card. Mahoney Mass and a Pivarunas Mass and only had those two choices, I would take the latter.
But seeing as I am an Eastern Catholic, I probably would avoid both. I know a lot of Byzantine Catholics who think the Latin Church ceased to be Catholic after Vatican II. Choiced between Pivarunas and Eastern Orthodoxy, I would take Eastern Orthodoxy, besides the Orthodox have their own share of wackjobs. (HOCNA, parts of ROCOR, the Old Calendarists)
Rome isn't the only game in town, even if Roman Catholics think so.
