'Liberals' don't believe that the thing being described is the killing of babies. It doesn't really work to take your perspective on a complex and grey issue and apply it to someone you disagree with who doesn't even share your perspective. Go up to a liberal and say, 'Hey, do you support murdering babies?' and they'll obviously say, 'No, of course I don't."
Actually, no. 'Liberals' are in favor of the choice of a woman to have autonomy over her body. Almost everyone, including liberals, is not in favor of abortions. They're traumatic, they can lead to serious health problems, and the overwhelming majority of people would love to see fewer and fewer abortions.
Again, if they believed that it was killing the innocent, they would be against that, but they don't believe that's what it is. Idk if this is ego grandstanding or what, but do you really believe that almost half of Americans are cool with murdering children? You would bet that tens/hundreds of millions of people are fine with that concept? Get real, man.
You said that at some point it becomes murder. I agree with you. The real tricky part is, what's the point? You even took the spiritual equation out of it - that's good, because that's necessary for legislature. So, is a morning after pill murder? I think anything past 21-22 weeks is, personally, but that's a long gap in between those two - when is it murder?
