"If I were the mother of a suffering child -- I mean a deeply suffering child -- I would be the first to want to put a pillow over its face," Ironside said in a video clip of a new BBC television interview she gave.
"If it was a child I really loved, who was in agony, I think any good mother would," she adds.
The host of the program was so shocked by the statement, that, as another guest was about to be introduced, she called the remarks a "horrifying thing."
But Ironside went further -- advocating abortions for children who are diagnosed in the womb with severe disabilities.
"If a babys going to be born severely disabled or totally unwanted, surely an abortion is the act of a loving mother," she said.
Reverend Joanna Jepson, the other guest, was left stunned in amazement at the comments. She was born with a severe birth defect, since corrected in a minor surgery, that left her top and bottom jaws considerably out of alignment. She has advocated for the rights of disabled children who are targeted for abortions even for minor issues such as a cleft palate.
Patrick Archbold responded to the remarks in a post at the National Catholic Register.
"This goes to show that no principle of civilization, no precept -- no matter how holy, authentic, or certain -- cannot be twisted into the service of evil. Murder as an act of love," he said. "If Ironside had her way, people like Jepson and her disabled brother would never have been born or perhaps lovingly smothered to death."
"You might think that all this is some wicked theoretical exercise on the part of Ironside, alas no. Ironside willingly recounts the tales of her two abortions. The second of which she professed to be for the good of her baby," he continues.
"Ironsides horrifying statements are the logical extension of many of the arguments in favor of abortion and euthanasia, but simply taken to their utilitarian ends. And she is not alone," Archbold concluded. "The only good that comes out of this is the glimmer of hope that such things still have the ability to shock."
