I'm pro-choice, but I'm not a one issue voter. I'm also not a woman, so even if I was a one issue voter, this wouldn't be the issue.
I see the pro-life point of view as valid, but for me, it's mostly a question of enforcement. I also think the golden rule is a wonderful idea, but totally unenforceable. Unenforceable laws bring contempt on the whole body of laws.
Also, we get more rights as we get older. At 16 you get to drive. At 18, you get to vote. At 21 you get to drink. etc.
I don't have a problem with all you pro-life folks. I see why you believe the way you do.
