The book
Good Bye Good Men gives a thorough treatment of the subject. It appears that many seminaries have been systematically rooted out the anti-homosexual and orthodox. Gay liberal candidates sail right through to ordination but most of them don't last long in the active priesthood. Seminaries firmly under orthodox control are bursting at the seams.
My sense is that most seminaries in the US fall somewhere in between these two extremes. Homosexuality is still tolerated but no longer forced. This would correspond to the typical behavior of JPII bishops who tolerate but slightly downgrade the proclamation of liberal heresy while energetically suppressing attempts at Catholic restoration.
Needless to say, the heartless, ongoing toleration of heresy and buggary is alienating and corrupting Catholic youth.
I spoke to Michael Rose about Sacred Heart Seminary in Detroit. While I think his assessment was accurate it was a situation that existed 5 or more years ago and something Cardinal Maida was trying to fix. Rose said he had heard things were better and I hope one day he will be able to write another book which speaks of improvement, until then I will pray for better priests. The situation in Detroit was pretty bad, St. John Seminary was one of the worst in the country and the process of correction started back in the 80s with Cardinal Szoka (sp?) when he closed St. John as a Seminary and moved the faculty and seminarians into Sacred Heart. You can argue about how long it is taking to clean up the mess but I am very pleased it is taking place otherwise I doubt there would be any seminarians.
