Not a bit of it, although to the extent that young (or old) people are pro-contraceptive, that's a sign that they need to be catechised and, above all, evangelized.
The prophets used a figure of speech, "uncircumcised in mind and heart," to describe Jews whose "faith" didn't reach into the nitty-gritty of their lives. It might be more useful today to say "contraceptive in mind and heart," unwilling to give and receive life.
Excellent point! I promise to plagiarize it and use it widely!
