“unbridled fornication” is encouranged by the contraceptive mentality. With that mentality rules, boundaries and common sense are thrown out the window.
“Perhaps the introduction of artificial birth control promotes immorality.”
It does.
“However, I cannot logically link the introduction of artificial birth control with unwanted pregnancies.”
I can. In every country where contraceptives were introduced, unwanted pregnancies increased rather than decreased. This is not a false association, but a natural result coming from the dominance of the contraceptive mentality coming from the ease and availability of contraceptives and the deformed culture which demanded they be produced.
“Of course, religious doctrine is not always based on logic.”
This is. It is also not religious doctrine. Contraceptives deform cultures. That is not merely a religious concern. It is societal and cultural. Even those with a secularist/liberal viewpoint have begun to notice this in the last two decades: Lionel Tiger and Francis Fukuyama come to mind.
Sorry. I still do not accept your explanation.
