Everyone on both sides of the whole abortion thing seems to be dedicated to arguing without actually coming up with a solution to the problem. The real question is "when is a fetus a person?" Nothing more. Nothing less. Here, take a few statements that I think 99.99% of humanity would agree on (unless they're a troll):
A 5-year-old kid is a person. If a mother decides she doesn't want the kid at that point, and kills him, that is murder.
An unfertilized egg is not a person. A mother is under no obligation to preserve the potential life represented by every single unfertilized egg. This is not murder.
So clearly the truth - the actual pivot point - lies somewhere between these. But practically nobody actually cares enough to, you know, discuss this - they're all wrapped up in "ABORTION IS MURDER" (leaving unspoken their belief that an embryo is a person) and "A WOMAN'S RIGHT TO CHOOSE" (leaving equally unspoken their belief that an embryo is not a person). And then they get into these insane battles over "well, you don't respect the mother and/or child" - when really, the only thing they disagree on is when a person actually becomes a person. It's like watching two mathematicians screaming about a geometry problem, not realizing that one of them is working in Euclidean space and one of them is working in non-Euclidean space.
So if you're going to fight about this, please identify the exact moment a person becomes a person in your mind, and explain why? Because that, right there, describes a great deal of your stance on abortion. And if there's anything in your mind beyond that particular cutoff point, figure that out too.
(No, the cutoff isn't necessarily everything - I can see arguments for abortion being legal for different reasons at different points. But it's most of it, and if you think abortion should be legal based on a conditional, then it seems reasonable that you believe in a sort of hazy proto-person at that point.)
