As soon as the Pill was introduced, birth rates plummet.
Yes. I am a Protestant and I was not brought up to believe that contraception was bad. Abortion was bad, yes, but only Catholics thought contraception was bad. Well, I do not believe in contraception. It is bad. I no longer see any difference between abortion and contraception such as the pill. These things have done great moral and demographic evil.
