Unfortunately, human beings are really, really bad at putting themselves in the shoes of others. Psychologists call this 'egocentric cognition' and it's most famously demonstrated by an experiment involving the whistling of common tunes.
I just can't understand the 'life trumps all other concerns' argument when many of the fetuses being aborted are indistinguishable from the billions that naturally fail (or are only a few weeks past that stage.) Sure, there's the question of intent, but...every single implanted embryo is a unique, precious person. Yet billions of them vanish without ever getting a chance at life. If a few more vanish due to human intent, why does that matter? If I had never been born, well, then, I guess that would be a bummer - but everyone else who is born is unique and precious too. My own presence or absence only matters to me. And the only reason it matters is because I was lucky enough to live. Billions of others weren't, largely for natural reasons. Had I been aborted, well, I wouldn't care, would I? It just wouldn't be a big deal.
It's like getting upset about the failed formation of whatever planet used to be between Mars and Jupiter. It probably would've been a pretty cool, pretty unique planet. But nobody cares that it didn't make it, simply because, well, it didn't make it! And Planet X wasn't formed either, and neither were ten billion other possible planets that might have been.
Sure, nobody blew up that planet while it was still forming (well, probably.) But it illustrates why we don't mourn over all the fetuses that never make it naturally. They had the potential to be beautiful human beings, but that potential was snuffed out by accident. No one cries over them. The difference you'd cite, of course, is that fetuses aren't being aborted by accident...and no, they're not. But I don't really see how they have more of a right to life than all those who die accidentally. They're all unique individuals.
There's a higher freedom to consider here, though. And that is the freedom to hold a view about morality and the world. If someone else doesn't believe the same way you do about the right to life, why do you have the right to impose your views on them? Isn't it the height of arrogance to believe that only you have correctly analyzed the world and synthesized a system of morality?
Conservatives do not have a monopoly on 'good' and 'right' and 'life-affirming.' Those with differing viewpoints can claim those values just as firmly.
