I wasn't trying to generalize, I think it's just a result of our difference of opinion. Both drinking alcohol and murder will happen anyway, but one involves another person's life and one doesn't. Since you don't think a fetus is fully a person, you think alcohol is a better analogy for abortion; since I do, I think murder is a better analogy (and also what I think it actually is).
And the question of what the fetus is is really where the debate should always be centered. If it's a person, killing it can never be fully justified (and incidentally, adoption needs to be simplified; there are already more than enough families willing to take in unwanted children, but it's so much work for both sides that it doesn't happen nearly as often as it should); if it's not a person, kill away (I don't buy the "potential for life" thing. The potential for life exists as soon as you have a guy and a girl in the same room. Once the egg is fertilized and there's a thing that's eating, growing, responding to external stimuli, and has its own unique DNA, it's alive. The only question is whether it's a person. That probably amounts to the same thing, but at least it's more accurate and honest terminology. I think I'm starting to make less sense and get more tangential now, so I'll stop. Parentheticals shouldn't be this long.).
