In the first place, the definition of life as beginning with conception is a religious one. In most discussions, it seems to be taken as fact. Not all religions agree that it is a human being with full constitutional rights, etc. upon conception. So the discussion is a religious discussion, and should be limited to pews and steeples rather than made a government intervention issue.

Having said that, I suggest that those who oppose abortion don't have one. I find it curious that one of the most outspoken abortion rights opponents, Leslie Unruh from (South Dakota? or somewhere out there) has had two abortions that she now would deny others. There is no middle ground. You are either pro-choice, where you allow others to have abortions, or you are anti-choice where you think the government shoud make the choice for women. The expression "pro-life" is not an accurate one. The correct and accurate one is "anti-choice."

It is also noteworthy that most opponents of abortion choice also would deny accurate sex education programs that might limit the need for greater numbers of abortions. It seems to me that they are not so much "pro-life" but anti-sex, period.
