Thank you for the dialog.
The heart behind contraception is this idea that children are not a blessing. The thing is, people are free in this country to use it or not use it; few are going to stop using it simply because the Vatican demands it.
So how do we facilitate less contraceptive use? By addressing the *heart* behind its use. Instead of simply demeaning those who use contraception (whether birth control or NFP), we should promote the value of children, show how God has given them as a blessing. That will facilitate less contraceptive use.
Some contraception is in fact abortifacient. We should educate Evangelicals (and others) about when it is abortifacient, so that they can stop killing pre-born babies.
I also believe in a positive message, but the Church must instruct its members and to be pro-life one must believe that promoting life is worth bearing the possibility of censure.
