I think its ridiculous to imply that abortion is the next logical step after contraception fails. The normal reaction to an “oops” pregnancy is “wow I guess this was REALLY meant to be, since we were using birth control!”
Blame abortion on casual sex if you must blame it on something. Contraception cam make casual sex easier but that by no means makes it automatically evil in itself. Anything can be used wrongly and people have been having abortions all throughout history. Plus, 50% of abortions have nothing to do w/ abc so casual sex can exist independently. Also you can blame the attitude about abortion in this society on the liberal agenda. “this is my body and I’m selfish so the life I’m carrying is insignificant and I can do what I want” (sounds like similar reasoning to what I hear about contraception. The selfish addition there is not always the case though). These people have reduced pregnancy to an inconvenience and have done their best to remove all human element. (now put “fertility” in place of the word “pregnancy” in this sentence and you got it

) It’s no longer a baby it’s a “choice”. (disgusting, yes)
Honestly from reading these forums I’ve never seen people more in dread of pregnancy than many of the NFP users. To them having sex with their spouse is akin to playing Russian roulette, so please stop pretending that nfp’ers don’t have a contraceptive mentality. I’m sure that some truly don’t, but by the same token not every contraception user is in dread of pregnancy. From what I discern from reading these debates, the only difference is the abstinence or “self control” with NFP. But not everyone puts their values there and most couples are not having sex more days than they are, naturally, so it’s not particularly important or thought of as virtuous to abstain out of dread of pregnancy to most people.
