The thing is, most of the younger RCs of my generation, as I've observed, are fairly devout, Traditional, orthodox Catholics, who want to 180 the post V2 turn around. These are Latin-Mass going, Holy Hour attending, rosary-praying, scapular-wearing, theological discourse writing, Trent-quoting Catholics who want to reform the reform. So expect the Post V2 liberality to die out in 20 years.
As much as I hear this from people online, I've yet to see it. The town I'm from had several Catholic parishes that weren't the radical progressive sort, but they were by no means trads - there was only a sedevacantist parish that would fit that.
Where I live now has several large parishes that are rampant with the progressiveness, even having a liturgical committee that plans liturgical dance etc. The college I go to is Catholic and I'm in the religious studies department, and it is rampantly progressive among the young and old. Feminist/liberation theology, inclusive language, pro-same sex marriage (in/out of Church), and some are no doubt in favor of women priests. This includes the young, many of whom are in pastoral ministry. Of those in pastoral ministry, many are musically inclined and work with local liturgical music and are into the modern hymns, guitars and all. And many are devotionally more into taize/visio divino/art prayer/etc than anything traditional, with the exception of a few who like the Hours or Stations.
The only exceptions to this where I'm now at are the few (I.e. extreme minority) conservative/trad Catholics I mentioned. And that comes to three or so. There is, however, one FSSP parish here, which was apparently resisted for quite some time by the former bishop.
And I went to Maria Stein, a retreat center located in a historically Catholic community, which even permits feminist Episcopalians to give lectures and lead retreatees in New Age/Christian taichi stuff.
In short, while I really wish what you're saying to be true, I just think it's only partially true at most.
