The answer to you is the same as the other posts I have placed here, particularly to Mortimer Snavely. The steril concept drives people out the door. It's one that people who are stuck for an explanation have put together and now sieze upon. Have you read my work published elsewhere?
I reject the notion that stopping the use of contraception creates alienation, and hardly seems irrelevant since it has direct links to abortion. Prior to the advent of contraception, the focus was on responsibility to family and life had more value. After the invention we see a slippery slope that took us to concepts of "free sex" on down until life has been devalued to the point where I am not sure we as a nation can get it back.
I suppose you think that if contraception isn't used then people won't be able to have sex without consequences and that for many is unacceptable . Well, I support natural family planning, and have found that people can still have sex without fear of an unwanted pregnancy if they are aware of how their bodies function and can read the signs of when they are fertile or not. They may have to abstain for 1 or 2 days out of the month, but if a person can't abstain for that small amount of time then they have serious problems. Contraception is wrong and immoral, and I will continue to voice my concerns against it.
