From the linked article,
“The Hartles, who say they’ve always supported abortion rights, have now formed the Ivy Grace Project, named after their daughter who died,..”
Unless she died in the womb and was stillborn the correct term is murdered. The daughter who she murdered. Re the article the defect was first found at 18 weeks and confirmed a month later. So the baby was at least 22 week along when the decision to terminate the pregnancy was made. I doubt that happened right away which means she may have been 6 months old when murdered in a most heinous manner.
Named after their daughter whom they killed.
If they have always supported abortion rights, there is no way they can claim to be conservative Christians.
