Liberals don't think that Vatican II has been implemented. They still wait for women priests and approval of artificial contraception.
Conservative (they call themselves-- Orthodox) Catholics live in denial that Vatican II was a failure for the Church. In private they will complain but when the subject comes up in public, they will defend the "Church" to the hilt with a Pollyanna enthusiasm: " ...every thing is great the problem is not the Council but the 'Spirit of Vatican II...' " Well if the "Spirit of Vatican II" controls or controlled the Church how does that happen? Who is responsible for implementing it?
The Traditionalists are more honest about the failure of the changes since the Council but become Pollyannas when talking about the "good old days." They think the church was perfect in the 1950 and earlier. From what I have heard the nuns, brothers, and priests were more like drill sergeants than Christian role models.
There was a need to reform before the Council but not the way the Council did it. The Council may have been protected from teaching heresy but not from imprudence. Very few have read all the documents of Vat. II because they are long, confusing, as a matter of fact, I believe the documents of Vatican II are longer than all the other councils that came before it combined!
