That's it. Those not formally part of the Catholic Church who are not culpable for this fact can be saved anyway. But this salvation is only possible because these people will be, in some mystical way, "inside" of the Church.
So, excatholics are going straight to hell, because we should know better? Or, am I misinterpreting your statements?
Many people are originally Catholic, Baptist, Moslem, etc because their parents decided for them when they were very young. These children do not have a choice in the matter. Many indoctrinated children choose different paths once they are free to choose. These people become ex-Catholics (Baptist, Muslims, etc) through no fault of their own.
Our society has wisely decided that children under 18 are not capable of choosing to have sex with an older person. Religion is a much more significant life choice than a sex act. We need to recognize that a child under 18 is also not capable of choosing a religion that is forced upon him by an adult.
