This is classic Modernist disingenuity.
Vatican II was not a "response" to the cultural revolution, but a deliberate capitulation to it.
In the 1960s, when society was in upheaval, it was most necessary for the Church to batten down the hatches (i.e., to double down on sound doctrine, Thomism, the decrees of Trent and Vatican I).
Instead, Angelo Roncalli decided to "throw open the windows of the Church to let in some fresh air." Except, unsurprisingly, he didn't let in fresh air - he let in a pestilent cloud of error, sin, and confusion.
This is the equivalent of a father seeing an F5 tornado approaching his home, and instead of leading his wife and children to the safety of the basement to weather the storm, he takes them out into the backyard to play on the swing set.
Do not be deceived. Responsibility for much of the misery, confusion, and sin present in the world today may be laid directly at the feet of the Vatican II robber council and the false popes who carried out - and continue to carry out - it's impious and heretical decrees.

Many critics will point to “fruits of V2” that are really just the results of the upheavals from the 60s…
