Come on, Stubborn. I think you don't even believe that. You are not understanding the words based on their exterior meaning, but rather engaging in ideological interpretation a priori via your beliefs. Even if I were a non-Catholic who couldn't care less what EENS's interpretation is and I was reading Blessed Pius IX's words there is no way I would come to your conclusion.
Then, you must be a non-Catholic who couldn't care less about dogma.
I've known a few of who Pius IX speaks of, i.e. whose ignorance was beyond their control.
One was only 2 years old at the time, now I think he's in his mid 20s. As a baby he was in the hospital for some virus and received some overdose that ended up going to his brain, making the baby all but a vegetable, still is today. Another was my own father who died with alzheimers. These are only two examples of people I knew personally who were in ignorance beyond their control, hopefully you get the picture of what he meant by "ignorance beyond his control".
What the pope said was not a clause, there is no clause in dogma, nor is Pius IX implying any such thing. If an insane person dies outside of the Church, that person has no
"hope for life or salvation unless he is excused through ignorance beyond his control." Now you can hypothesize and theorize whatever far out scenarios you want to hallucinate about this, but whatever you come up with will never change or expose any clause in the thrice defined dogma. That's how dogma's work.
