Surely it's of equal importance? If you contend (as I do with regard to abortion) that "personhood" requires you to be born and start to assimilate environmental information that will eventually help you determine who/what you are, then the ramifications of saying "personhood begins in the womb" with regard to FAS can be seen to have horrific anti-choice implications with regard to aabortion, because the issues will be conflated - "if personhood begins in the womb with reagrd to FAS,, then surely it must begin in the womb with regard to
everything?"
