People who argue from the fringe view that "life begins at conception" and "a fetus is a human being" often bring in a lot of other fictions about abortion, like that it isn't safe for women, that it's murder, whatever.
It isn't.
It's also none of your business what other women do with their bodies or with their doctors. Wishing that it was your business (or telling fantasy stories based on your fringe views) does not make it so.
So mention this when you argue with such a person, or someone who specifically argues these points.
I did not argue that "life begins at conception". As for "a fetus is a human being":
A fetus is: "an unborn or unhatched offspring of a mammal, in particular, an unborn human more than eight weeks after conception"
Hence, a fetus is not "at conception", but at least 8 weeks later. According to Wikipedia on US law: "Viability is usually placed at about seven months (28 weeks, approx. 196 days) but may occur earlier, even at 24 weeks"; In other words, a fetus may be aborted 24-28 weeks after conception; Arguing that a fetus in this range is a human being is not a fringe view among those who look into the issue, or at least that a fetus might be a human being (it's possible that we don't know enough about human development in the womb to decide).
> It's also none of your business what other women do with their bodies
What women do to the bodies of fetuses is the issue here. A woman who murdered her unborn, viable child would be charged with muder despite it concerning "what she did with her body".
> Wishing that it was your business (or telling fantasy stories based on your fringe views)
The law does not.
The governing bodies of the US have repeatedly affirmed that access to abortion is a woman's right.
The medical view of abortion is that it is a safe, legal medical procedure.
Whatever you believe--and you are free to believe anything--about fetuses changes neither the legal view nor the medical view of abortion.
