Abortion was and is a manufactured issue for most non-Catholics in the conservative movement in the US. It doesn't reflect a consistent ethic, it reflects cultural symbolism around reproduction and gender roles.
In all fairness, it was one of those reactionary issues where the vigor with which pro-life people fought to restrict abortion was coupled to how much the pro-choice side was was trying to expand it.
Through most of my childhood and adolescence, I remember the Clinton/GenX-Democrat position of "safe, legal, and rare" being one that, while not meeting the "ideal" of either of the polar extremes, was one that 70%+ of the population was willing to tolerate and let sleeping dogs lie for the most part.
The rejuvenation of the efforts to ban it as much as possible were a direct response to the efforts to try normalize and expand it.
As soon as the "rare" in "safe, legal, and rare" was scrapped for a more maximalist position of normalizing late term abortion, and repealing the hyde amendment, that was the kindling.
"Well, why should it be rare, it's not a bad thing?, so we're going to advocate accordingly" was just begging to rejuvenate the extremely staunch pro-life sentiments that had been rather dormant for a few decades.
FYI, the modern polling would indicate that the safe, legal, and rare (with reasonable term limits, and special exceptions for the 3 edge case scenarios) is still acceptable to well over 60% of people in the US.
However, per NPR:
That's reflected not only in an increased willingness to be unapologetic about having abortions, but also in the politics of abortion rights. The 1990s-era Democratic slogan "safe, legal and rare" is now deeply controversial, and many abortion-rights activists consider it inherently stigmatizing.
In fact, when people like former Planned Parenthood President Leana Wen and 2020 Democratic presidential candidate Tulsi Gabbard said they wanted abortion to be "safe, legal and rare," they were met with backlash.
When a former pro-choice democrat and a former president of planned parenthood are getting booed by their own tribe for merely suggesting "abortion is an unfortunate necessity, but not something that should celebrated, over-normalized, or propped up as some sort of beacon of empowerment", that would indicate that the left
lost the plot as much as the right did.
