Contraceptives will fail. Not just can, will, they have a percentage failure rate, I think condoms is 97%? That doesnt mean that in your entire life you have a tiny chance of it failing... That's the misconception here... It means that if you have sex with a condom 33 times - on average, one of those times, the contraceptive will fail. That won't always result in a pregnancy of course but there's always the chance.

The pill fails (had it happen), the coil fails (had that happen). Even vasectomies bloody fail. In fact the ONLY certain forms of contraception are abstinence, and full hysterectomy (if there's no uterus, there ain't going to be a pregnancy).

So yeah... Your choices are abstinence for all, unwanted babies for some, or abortion being a thing.
