As a former seminarian, it always surprises me that this is "news". This is something that those of us who were, or are still, in the butcher shop have known for a long time. The same individuals that caused us straight seminarians to keep our doors locked at night didn't just disappear. It stands to reason that those who recruited the gays eventually succeeded in paving the way for their gay recruits to achieve positions of even greater power and influence than they enjoyed.
A priest recently told me that the problem hasn't gone away. The homosexuals and cultural Marxists have just gotten better in disguising themselves when needed.
