If you look objectively at the arguements, then it's hard to argue against the logic that life begins at conception. It's the starting point. Bar none. Any other arguement, such as for life beginning with the heartbeat is really just arbitrary and so one has to conclude that abortion at any point is wrong.

Now I do add stipulations for myself, and you can debate those. Mind you I'm not a religios zealot predisposed to be against abortion. I also would argue that allowing abortion breeds irresponsibility, but I understand that arguement that it would be best not to bring a child into an unstable family. Either way, for myself I am accepting of abortions in pregnancies that endanger the life of the mother, are assured of severely handicapped children, or in the case of rape. For me all abortions would have to take place within the 1st trimester only. If you don't fall into one of those categories, then perhaps you should invest in birth control or abstinance. I think that's a pretty good compromise.
