E.g. (IMO):
33. Through his labors and his native endowments man has ceaselessly striven to better his life. Today, however, especially with the help of science and technology, he has extended his mastery over nearly the whole of nature and continues to do so. Thanks to increased opportunities for many kinds of social contact among nations, the human family is gradually recognizing that it comprises a single world community and is making itself so. Hence many benefits once looked for, especially from heavenly powers, man has now enterprisingly procured for himself.
But when I see what was done in the name of Vatican II, that's when I agree with you wholeheartedly.
Even if the intention was not to tear down the sides of the sheepfold and abandon the sheep to the wolves, it was certainly the outcome. Religious relativism is inevitable when traditions and disciplines that are visibly and distinctly Catholic have been discarded and trampled in order to appeal to those who are open to the Gospel but perhaps not to the Catholic Church. While the focus was on wooing those outside the Church, many within Her have wandered off. At best, the current ecumenical approach is based on the naive presumption that emphasizing common elements leads to conversion. This approach is similar to a business that conceals its unique, proprietary product in the back room while displaying commonly available products in the front window in an effort to attract customers. Jesus Christ - His Body, Blood, Soul and Divinity, His Eucharist Presence, is forgotten, reverence is abandoned, and the Church is falsely perceived as just one among many. This IMO is the rottenest fruit of VII.
It's probably also the source of all the other problems (disciplinary, moral, etc.).
