What changed your mind?
I had a huge prejudice against the Church because I thought Catholics (and believers in general) were unthinking, unquestioning, unreflective, not adventurous freethinkers like myself. And the pro-life people were, to my mind, right-wing fanatics, or well-intentioned naive middle-class women who had always led comfortable lives and didn't know the Real World Situations that caused women to have abortions.
In other words, I had swallowed the stereotypes whole. Plus, I couldn't imagine being on the same side as Jesse Helms.
What turned me around was tha I met some of these believers and found them good thinkers, able to ask and answer questions, able to give an account for their faith; as well as realistic, good-hearted, genuinely committed to the well-being of women in crisis pregnancies, etc.
It was the patient good-will and reasonableness of the Capital C Catholics that turned me abound.
Hm. Three paragraphs here. Oh, the stories I could tell! Boy, I do go on...! :o)
