Want proof? In 2011, a Notre Dame Board of Trustees member was pressured to resign because of her donations to a pro-choice group. Not only did the National Review not have a problem with her resignation, they published a feature criticizubg Notre Dame at length[1] for appointing her to begin with and in general not upholding pro-life only Catholic values.
So you'll forgive me if I think this article is bullshit and its arguments completely specious.
I await your downvotes.
