#ShoutYourAbortion, a movement acclaimed by former Planned Parenthood president Cecile Richards, began in 2015 when Seattle bartender Amelia Bonow had an abortion at a Planned Parenthood clinic and shared on Facebook her “near inexpressible level of gratitude” for it, reported KUOW. When Bonow’s friend, Lindy West, shared that Facebook post on Twitter, other women began touting their “abortion stories” as well.

By the way. Multiple abortions exist and are pretty common for all the reasons that life and people are complicated. If you would like to share your abortion(s) story with us, we invite you to do so at https://t.co/AtHIbQoKtO. 💛💛 #shoutyourabortion pic.twitter.com/XvkEK0PMS0 — #ShoutYourAbortion (@ShoutYrAbortion) November 14, 2018

None of the “stories” in the book express sorrow or apology for having an abortion. In fact, Bonow said she hopes the book will foster a normalization of the procedure. She said nothing about abortion ending an unborn human life.

“Our culture is all warped about abortion because the anti-choice movement has made abortion seem like a bad thing that bad people do, instead of a normal thing that normal people do,” Bonow said, adding she is “proud” of women who have had abortions.

After my abortion I felt relieved — and I’m in the majority https://t.co/7xZaPgc7ZD — #ShoutYourAbortion (@ShoutYrAbortion) November 2, 2018

“We should be proud of surviving all the things we’ve survived, and for choosing to love ourselves,” she said.
