Yeah, he's been reading too much Schleiermacher.
The Neo-Trads use almost the exact same tactics and same sayings that the Neo-Modernists and other Liberal Catholics used to bring down the church. See the Quiet Revolution in Quebec, specifically the change in religious mentalities that lead to it.
You woulnd't perhaps have any references, would you?
I assume that you mean the Quiet revolution in Quebec and not Schleiermarcher.
A book on this which covers that the changes that were happening in Quebecois Catholic settings before the 1960's is
The Catholic Origins of Quebec's Quiet Revolution, 1931-1970 by Michael Gauvreau, MQUP, 2005. Gauvreau focuses on Catholic Action groups and how, while some of them may have started with noble goals from a Traditional Catholic point of view, they fell under the influence of existentialist personalism, even radical versions of personalism.
I haven't read the whole thing, but of what I have, a few things stuck out at similar to those used by Neo-Trads and their sympathizers. Here are some excerpts:
pg. 31:

The Hertel spoken about here is François Hertel who's real name was Fr. Rudolph Dube, SJ. He was eventually expelled from the Society of Jesus, left the priesthood, and ended up in agnosticism I believe. He was also close friends with the liberal of French-Canadian liberals, Pierre Trudeau. Hertel's error as when can see from above is similar to that of the Americanists.
Also pg. 31:

pg. 322:

A few other notes:
1. The personalist-revolutionaries pushed a vague notion of "love."
2. Promoted a TOB-like view of sex.
3. Accused those who disagreed with them (the hardliners aka and traditionalist-conservatives) of being too puritanical, medieval, or jansenist, etc.
4. Wanted to de-emphasize Catholic teachings on sin and its seriousness.
