Your birth rate and your Pope is on you guys
You're correct.
But as I've pointed out here before, it wasn't the Catholics in this country who broke first on the birth control issue; it was the Protestants in the aftermath of the Lambeth Conference. In some sense, it's amazing the Catholics held out for the thirty years they did; knowing how many children they were going to have (two), the Protestants were free to buy bigger homes, a new car every two years, and take bigger vacations.
Unfortunately, keeping up with the Joneses became more important than keeping the Faith, and the Catholics succumbed.
That is a ridiculous argument
Officially sanctioned and approved birth control by Roman Catholicism.
