Well no, not quite. They weren't exactly kicked out -- they were rejected as suitable priest candidates for their particular diocese. This is another reason why the heterodox bishops have a priest shortage: because the screen out those candidates with "unacceptable" views. Like what, you ask?
According to what I've read, men who believe in an overly "conservative" view of the Pope, Mary, the Saints, the magisterium, the Real Presence, etc. I've heard of men who were screened out simply because they subscribed to Latin Mass magazine. Any stuff like that will often result in being screened out by the wiccan "religious" who serve in these capacities.
I believe the so-called priest shortage is manufactured by people whose agenda is served by the lack of good priests.
