Those are estimates, not facts. If Cozzens is basing his estimate on his experience while running St. Mary's Seminary and he did nothing to expel homosexual seminarians, thus violating the 1961 Vatican decree against ordaining homosexuals, then he is part of the problem and should be defrocked himself.
How can any Homosexuals be allowed to be Priests much less 50% of the total.
The Vatican formally stated in 1961 that homosexuals are not to be ordained. Those bishops who have thumbed their nose at the Vatican should be defrocked. Why do you keep capitalizing the word homosexual?
