The major problem with Vatican II was there was too many protestant theologians involved. And that is fact. Protestantism creeping into the church was the worst thing that came out of Vatican II. It’s like a cancer and must be weeded completely out.
How does the Catholic Church allow heretics to get involved in their business? When has that ever happened in the history of Holy Mother Church?
You also give way too much credit to the “outsiders”. Vatican II’s issues was more of an internal problem.
