They use this argument to not only fight against abortion, but to argue against emergency contraception pills, like Plan B.
However most people with even a rudimentary understanding of biology recognizes that a fertilized human egg is really not viable at conception, and in fact multiple billions of them never make it past the fertilization stage.
If you do not believe me, then here let the Mayo Clinic explain it better:
Weeks 1 and 2: Getting ready
It might seem strange, but you're not actually pregnant the first week or two of the time allotted to your pregnancy. Yes, you read that correctly!
Conception typically occurs about two weeks after your last period begins. To calculate your due date, your health care provider will count ahead 40 weeks from the start of your last period. This means your period is counted as part of your pregnancy — even though you weren't pregnant at the time.
Week 3: Fertilization
The sperm and egg unite in one of your fallopian tubes to form a one-celled entity called a zygote. If more than one egg is released and fertilized, you might have multiple zygotes.
The zygote typically has 46 chromosomes — 23 from you and 23 from the father. These chromosomes help determine your baby's sex, traits such as eye and hair color, and, to some extent, personality and intelligence.
Soon after fertilization, the zygote travels down the fallopian tube toward the uterus. At the same time, it will begin dividing to form a cluster of cells resembling a tiny raspberry — a morula.
By the time it reaches the uterus, the rapidly dividing ball of cells — now known as a blastocyst — has separated into two sections.
The inner group of cells will become the embryo. The outer group will become the cells that nourish and protect it. On contact, the blastocyst will burrow into the uterine wall for nourishment. This process is called implantation.
The placenta, which will nourish your baby throughout the pregnancy, also begins to form.
The fifth week of pregnancy, or the third week after conception, marks the beginning of the embryonic period.
This is when the baby's brain, spinal cord, heart and other organs begin to form.
The anti-abortion movement likes to use truly horrific images to upset people, but the facts are that the majority of abortions happen during the first trimester when the zygote/fetus is really one or two inches long, and it still quite undeveloped.
And if a woman takes an emergency contraception medication the chances are extremely good that the fertilized egg has not even attached itself to the uterine wall yet. And therefore is not yet, by medical standards, a viable pregnancy.
You would think that knowing that, anti-abortion activists would be all for contraception, both preventative and emergency, but they are not.
And the reason they are not is because this has nothing to do with saving potential human beings, and everything to do with oppressing women and making sure that there is a cost to any recreational sex that does not abide by the rules dictated in their morality.
