Abortion glossary :: Birth
Birth is when a newborn is demonstrably capable of, and successfully are, surviving independently outside of the womb.
Debating strategy
When an anti-abortion person describes birth as "a change in location" in their argumentation, they're attempting to control the narrative by ignoring the dangerous process of birth, and an appropriate response is to trivialize the absurdity of their point by reminding them that every person's location is constantly changing since our entire solar system is moving at a speed of approximately 828,000 kilometers per hour through our Milky Way Galaxy, which in turn is estimated to be travelling through space at approximately 2.1 million kilometers per hour.
