And, BTW, that title should be no problem to most of us IMO.
Before that America was literally founded (in the north at least) by religious conservatives who were too prudish for Europe. In fact the early US Quaker movement banned sex all together.
See, for example, http://www.challies.com/quotes/the-puritans-and-sex which quotes quite a few Puritan writings.
The point was to show the contrast -- the Puritans were only pro-celibacy for the unmarried, which they viewed as a temporary state; they had a pretty one-sided "everyone should get married and have lots of sex" view. They themselves considered this to be in opposition to RC views. (And, in particular, comments about the Puritans being anti-sex are way off base.)
