What your argument seems to be missing when discussing the right of individuals and free will is the fact that abortion is not a solitary action, but takes the life of another. Trying to buffer this by focusing on the "choice" of the mother (and yes, she's a mother when pregnant) and not considering the cost in human life has far greater consequences than personal rights.

Unfortunately there are too many organizations and politicians who profit from "choice" to effectively move public opinion away from abortion.
