I think I'm in the camp of most Americans on the subject- accepting of abortions as long as there are restrictions on when they can be performed. Many states are setting the limit at between 15 and 24 weeks, which is around four to six months, out of what is normally a nine-month period. I'm not sure if 24 weeks is too long, but I don't think it is too short.
I take some exception to the idea that it's not for "us" to decide, especially if the criteria is that I'll never become pregnant and thus the choice of having an abortion is one I'll never have to face. Does this mean that only people on Death Row should be allowed to discuss the pros and cons of capital punishment? That only people who have fired a gun or been shot should be the only ones discussing gun control? I don't think it works that way in the context of a human community/society. I think it's more important to be able to confront the issue and see what agreement we can come to, based on a reasonable approach to it.
