"Cruelty to animalsIs morally wrongBut cruelty toPrenatal human lifeIsn't.""Prenatal human lifeIs disposableBut postnatal human life Isn't.""Siamese twinsEach have their own bodyBut an expectant motherAnd her developing childHave only one body,Hers.""I believe in God,But I believe people,Not God,Have the rightTo chooseWhich prenatal lives liveAnd which onesAre eliminated."Pro-abortion argumentsSeem to depend onDenying the humanityOf prenatal human lives.It's not unreasonableOr unkindTo sincerely believePrenatal human lives matter.
