No one has any right to interfere with the self autonomy of any woman's body, period.  In order to extend the privileges of a born human to a fetus, you'd have to override the mother's body and her rights and force her to gestate.  There is no way around this - you'd be treating her like a brood mare and not an autonomous human being.  Pro-life activism is misogynistic, immoral and could lead to atrocity akin to forced sterilization.  Once a woman loses autonomy over her own body which means losing her status as a full human worthy of the right to her own life, she, since she doesn't have the ability to choose what happens to her, can also be forced to terminate a pregnancy at the will of others.  There are many unwilling fathers that would want this.

Think this couldn't happen?  Consider this:  a woman in Ireland denied an abortion at 8 weeks was forced by the state to carry the fetus and at 25 weeks the state forced a c-section on her.  This is an atrocity.
