Can someone be both?
I don't think that someone who claims to be both is necessarily confused. Life and choice are not opposites.
It's sad that so many people immediately think that this can only refer to political positions regarding laws. There is no recognition that pro-choice can also refer to giving women support and options so that they have genuine choice, and that pro-life can mean doing something practical to address the factors that cause many women to seek abortions.
As someone who is both pro-choice and pro-life, this is one organization that I'm willing to support:
I heard the founder of Efrat speak a couple of weeks ago. They don't demonstrate. They don't use scare tactics or guilt trips. They simply have social workers who process abortion referrals pass on their number to any woman who says that she wants to abortion for economic reasons. These women are offered practical assistance with baby goods, and they also have a program to provide job training with free childcare so that the mothers can lift the family out of poverty. They also have workers and volunteers to provide emotional support as well.
