"Has anyone, after claiming to be 'pro-life', had [or assisted in] an abortion in secret and then come forward and spoke about their decision?"

Is that what you were trying to ask?

Also, afaik, no. I've seen posts from abortion providers about seeing protesters come in [or bring in family] for abortions and then the providers saw the patients back on the picket lines. Never saw anyone who had a 'moral' abortion admit that they'd done it.
