From the article:
In the clinic world, repeat visitors are called, not unkindly, "frequent flyers." The reason that casual term is not an insult is simply due to how common multiple abortions are. "You have 300 possibilities to get pregnant in your life," says Peg Johnston, the director of an abortion clinic in Binghamton, New York. "A one percent failure rate -- assuming the best possible use of contraception -- is still three abortions," she says. "In what endeavor is a one percent failure rate not acceptable?"
According to Planned Parenthood, two out of every 100 women aged fifteen to forty-four will have an abortion this year and half of them will have had at least one abortion previously. Yet virtually everyone I've talked to about multiple abortions said she shouldn't have let it happen again, implying it was her fault.
