I don't know whether you can find out exactly which schools Freitas studied or not (I read her book, and don't recall a list, but maybe it's there).
If you can, cross-reference it with the Cardinal Newman Society's list of "authentically Catholic colleges" and get back to us. You won't find much of an overlap, IMO.
It should be obvious to any conscious reader that someone who dismisses Catholic teaching on sexuality as "silly" or "outmoded" isn't operating out of a surfeit of devotion to Catholic teaching.
No. I really suspect that we’ll get FR Catholics discounting the study for one reason or another.
And so far, I haven’t been disappointed.
