Why must they constantly lie? They lied to SCOTUS about two women being raped, thereby spitting in the faces of all real rape victims to push their money-making libertine agenda. They tel bald lies (ravi and Anguille come to mind) about forcing women to carry when it'll kill them. They lie about the scientifically verified fact that a fetus is a human life, being both alive and human. They lie about the fact that a rape victim can take Plan B to prevent a pregnancy in the first place and that very few abortions involve rape and incest. they lie to women about their being pregnant and the development of the child inside them and rail against showing them sonograms or informing them about fetal development or adoption.
Why must they base their entire case on lies if they support a 'good thing'?
I'm fairly certain I've never lied about any of those things, yet I'm still in favor of abortion being legal.
For me, the issues are viability and thought. I consider the ability to think to be the more important distinction, although I have no idea how to accurately gauge it. Basically, in the same way I don't feel any compunction about 'pulling the plug' when it comes to people in a vegetative state, I don't care about abortions performed on a fetus who's brain has not yet developed enough to think. Unfortunately I have no idea if our understanding of the brain and ability to monitor it are such that we can determine such things in a developing fetus.
I also believe that what will make abortion eventually become, if not obsolete, at least much less frequent than it is now, is technology, not morality. I think more advanced and easily accessible forms of birth control will be what reduces abortions to very minor levels. People are going to continue to have sex, and many will be very cavalier about the consequences; that seems unavoidable. If we end up with safe, extremely effective, long-term birth control, which is both affordable for all and easily and safely reversible or removable, that will have a much greater impact than morality, which is so variable.
I'm rambling and not paying that much attention to what I'm typing, so I'll just stop now
