They like that people are taking more personal responsibility to avoid getting pregnant in the first place, and therefore not committing what they believe to be murder in the form of abortion.
They also like that liberal minded people who consider abortion an option for an unwanted pregnancy are now increasing their rates of voluntary sterilization, thereby decreasing their future contribution to the gene pool.
This could be some side-effect, but your political ideology is not genetic and therefore self-sterilization has zero impact on the country's future political makeup. Anyone making that argument fundamentally does not understand genetics and child raising. Even within families, children will often hold wildly different political views from each other, let alone their parents.
In conservative circles, it's become a sort of meme. People running out and deciding to become responsible after the "safety net" was removed in some select areas. It should be noted that repealing of Roe had zero impact on significant portions of this country - making the meme even more funny within conservative circles.
From some conservative's perspective, sure, no abortion is permissible. But that is a hard-liner's perspective, and just like the Democrat party has shifted enormously over the past few decades, so is the Republican party.
There are fewer and fewer hard-liners, and more and more folks that just think abortion is supposed to be a last resort - not the first resort.
To that end, this was a clear win for that perspective. I think more of us can agree on this perspective than we would think...
