From Jezebel, a gem of hypocrisy:

I was a very naive 21 year old in the mid ’80s and was surprised to learn that a fellow acting student, a beautiful Catholic girl from Philadelphia, had a standing appointment every six weeks or so with a gynecologist for, what she termed, a menstrual extraction. By that point I’d taken my roommate to an abortion clinic in the central part of the state and was pretty well-versed in birth control methodologies, but I’d never heard the term menstrual extraction before. I asked my classmate what that was and she said it was a procedure wherein the doctor extracted the uterine lining, thus making one’s period much shorter and more convenient. She then explained that most of the Catholic women she knew, all well-insured and well off financially, had the procedure done regularly. Unthinking, I blurted out, “But isn’t that the same as an abortion?” “Oh no,” She replied very seriously. “By having it done regularly, it’s just a medical procedure. No sin involved.” Now, more than a quarter of a century later, no longer naive and somewhat jaded, I find I’m still boggled by this.
