What that person meant was basically the difference between left and right or pro and anti abortion:
There right wants to ban abortion for everyone in fear of even 1 abortion that would have been a perfectly fine baby. (Which they would perceive as murder)
The left wants to allow abortions for everyone in fear of even one forced birth leading to a death. A death that was preventable by a abortion.
The right of a baby to live DOES NOT "TRUMP" THE RIGHT OF THE WOMAN TO CHOOSE. End of debate.
They are incredibly different perspectives.
