For me, my stance has nothing to do with my respect for the sanctity of life... rather, it's a control issue.
I simply feel the need to control the reproductive freedoms of others. If I could, I would put a chastity belt on every man, woman, and child in this country (except, of course, for myself) opening them ONLY when procreation is desired, registered and approved.
I have developed my stance on the issue with premeditated spite and the utmost malice toward any freedom loving American.
Legal Disclaimer: Actually, my Pro-Life view stems from the fact that murder is universally illegal, and I see no reason for exceptions to those laws simply because the victim breathes fluid rather than air. I am Pro-Choice in that people can either choose not to ####, or they can choose to protect themselves if they do. Barring that they can choose to eat a morning-after pill. But once there is a baby, the choice is already made. And I don't think you can "unchoose".
Maybe Pro-Choice people should change their name to "Pro-Unchoice. It seems more accurate.
