From talking with priests who are spiritual directors and priest psychologists and psychiatrists, as well as retired priests. They will all tell you how homosexuals were screened out of seminary in the first half of the 20th century.
I think this is wishful thinking on your part.
Think whatever you like.
And how would they know this? Do they have access to diocesan files?
Homosexuals who don't want to be found out will not be found out. There were no "priest psychologists" in seminaries in the first half of the 20th century.
