The Elephant in the Room with Trump Supporters

Abortion is the elephant in the room that keeps many conservatives loyal to Trump.  They believe abortion is murder.  In contrast, Liberals believe on day A it is not murder, but on day A+1 it is murder.  Perhaps we need to discuss what happens between day A and day A+1.   What happens that a fetus becomes a baby on day A+1.  What constitutes human life?  And how is it that human life forms between day A and day A+1.   Perhaps we should add an extra day of safety, and then another, and another?   Until we can discuss what happens on day A+1 to turn a fetus into a human, the elephant will stay in the room.  I would prefer that we make an extraordinary human effort to have no unwanted pregnancies and no unwanted babies in this world; is that impossible?
