In modern times, it opens up the door for allowing transhumanism, which advocates human experimentation, eugenics, genocide, euthanasia. Note how many of the biggest transgender treatment centers were once primarily abortion clinics. There's a connection there.
Interestingly, I remember when pro-life people used to support abortion in cases of rape, incest and potential harm to the mother. Those were considered "reasonable" opinions to have at that time, even among hard core Catholics I knew personally.
The fact that there are pedophiles priests doesn't negate the fact there are pedophiles everywhere.
I've experienced pregnancy, one that wasn't well timed or planned, so I don't take it lightly. However, I see transhumanism as much greater threat to humanity at large than unplanned pregnancies. Besides, I'm sure there will be "technological advances" which make abortion a thing of the past in a few years. Women who shriek about Roe being overturned don't realize that transhumanism, which is funding leftist politics, wants to eradicate women from the earth, as they see us as "useless eaters", they see us as "environmental hazards", and despise the fact we can breed without technological intervention. Transhumanism wants to control reproduction, and women are the barriers to that goal for them.
