Ayn Rand was pro-life in the most meaningful sense of the phrase:
For centuries, the battle of morality was fought between those who claimed that your life belongs to God and those who claimed that it belongs to your neighbors — between those who preached that the good is self-sacrifice for the sake of ghosts in heaven and those who preached that the good is self-sacrifice for the sake of incompetents on earth. And no one came to say that your life belongs to you and that the good is to live it.
The world would be a much better place if people took ownership of their lives and lived them for something grander than superstition and servility to power.
