> That is absolutely false and made clear in the Catechism (though abortion is, fundamentally, not a matter of faith, but of ethics, contrary to popular misconception).

A bit nit-picky, but while all authoritative documents (like the catechism) unequivocally condemns abortion, there is no shortage of Catholic scholars who are pro-abortion. Just like the Pontifical Commission on Birth Control. The scholars gave it the green light, but not even having “Pontifical” in the name made it remotely authoritative.
