I’ll try to reply

But I didn’t see a question in your post, so if I don’t hit the mark, ask.
I’m not sure what kind of reply you wanted to your post. The fact is, most Catholics don’t understand the Church’s teaching on artificial birth control, and that hinders their compliance. What adds to the equation is that they are ignorant of NFP to space out or prevent pregnancies. That doesn’t make it right. It only means they’re not following the rules.
People are afraid to have more children than they can afford, and are ignorant of Natural Family Planning, and go on birth control. People are afraid to have more children due to medical reasons, and are afraid to get pregnant, and afraid to trust the efficacy of NFP, and go on birth control instead — resulting in even more health concerns. People also get frustrated listening to the hot air blown by scrupulous Catholics, and instead of researching and learning, they give up and succumb to the easy way out that is birth control. That doesn’t make them good Catholics, that just means they are noncompliant with the Church’s teachings. And then there are some who were taught that the use of birth control is a matter of concience and use their conscience to dictate their decision.
Your statistics are true, but that only means that the Catholics using artificial birth control are either purposely using birth control with the knowledge that it is forbidden and know they are in mortal sin; or they are ignorant of the reasons why the Church forbids artificial birth control. People just are not educated about Catechism anymore.
I am 40 years old and it wasn’t until I joined this forum that learned the reasons WHY the Church forbids artificial birth control, and that the Church allows married couples to use Natural Family Planning (which is NOT the old rhythmn method) to space out, or delay indefinitely, pregnancies. That’s pretty sad since I went to Catholic schools from 5th grade through college. I had a completely different perspective of ABCs before I came here.
I have found that the majority of Catholics do not know WHY artificial birth control is against the rules of the Church. When most people that I encounter IRL learn that artificial birth control causes abortions, they seriously reconsider it. I don’t know what they do about it after that, I but do know they are shocked to learn that it does, and become aware of the rules of the Church and why they are made rules. Most people also don’t understand the unitive requirement for the marital embrace. I admit, the unitive aspect of the marital embrace and the rationale given by the Church that ABCs of any kind hinder the unitive aspect doesn’t sell me. In fact, I think it’s utter nonsense. But the thing about being Catholic is that you need to follow the rules as best you can despite disagreeing or not understanding the rules. It won’t be the first or the last teaching of the Church that I either don’t get or disagree with. But I try my best to follow the teachings.
I also find that no one else that I know IRL knows what Natural Family Planning is, which is pretty sad because in my “other” life, I was surrounded by Catholics. But when I explain NFP to them, they are intrigued because NO ONE I know IRL likes ABCs. They go from the Pill, to the diaphragm, to others, to back to the pill, etc. Because they don’t like the side effects and other problems. The older we get the more NFP is a rational option due to the health risks. Religious teaching aside, I think it is a grave injustice to women not to educate them about NFP.
As to using ABCs NOT being Christian, I already answered that and said I didn’t agree with it. Many other denominations, and even the Jewish religion, allow birth control. So if someone is faithfully following their faith (which the Catholic Church acknowledges), one can’t say that they are not being Christian because of it because they are in fact following their faith, and not breaking the rules of their faith. The Catholic Church is the most strict regarding this matter, and can’t expect people of different faiths to be just as strict when their religion allows more leniency. It’s just an unreasonable expectation. They don’t have the same knowedge that Catholics are supposed to have. That’s why my original answer was stated as it was.
