The "potential person" argument is pretty weak.
Explain why.
Aside from imposing religion, pro-lifers tend to get confused between 'potential' and 'existing'.
The "potential person" argument makes menstruation murder, which is obviously not the case. The pro-life argument (if I am not mistaken) is that a developing fetus is indeed a person, and not just a potential person. I have heard pro-lifers support this on the basis that the fetus has a full human genome and is thus distinct from either parent. (Aside: this fact is why the mother's immune system acts wacky during pregnancy, and often kills the fetus because the immune system recognizes it as non-self) An individual unfertilized egg is derived wholly from the mother, containing only her DNA, and so would be considered a part of the mother, and there is no crime when an egg is disposed of. But at the point of conception, two people's DNA combines to form a new person's genome, and it is here where pro-lifers say we can clearly demarcate the creation of a new person.
Premise 1: Developing fetuses are individual humans.
Premise 2: Killing humans is wrong.
Conclusion: Abortion is wrong.
Since no one is likely to contest Premise 2 and the logic is valid, the debate has to move to contesting Premise 1. It honestly just becomes a game of definitions. If you accept pro-life definitions, you are compelled to accept pro-life conclusions, and similarly if you accept pro-choice definitions, you are compelled to accept their conclusions. But who has the more correct definitions?
