No, Fuentes is NOT giving a blanket allowance for abortion “for the life of the mother” or in “rape.”
"if everyone was having sex within marriage", then "All children would be planned." is false.
"if everyone was having sex within marriage", then "the only time you get an abortion is if it is a form of birth control" is false.
"if everyone was having sex within marriage", then "there would be far fewer" abortions might be true.
He should've said this, which is certainly true: "If abortion is criminalized and punished, then there would be far fewer abortions, because most citizens are law-abiding."
