The estimate is that somewhere between 3% and 5% of women in this country use NFP.  It is not high in most countries where women are educated and contraceptives widely available.  They represent a very small percent of Catholic women and so represent a view held by only a very small percent of women who have the choice.  

I do not say that women who use NFP should be excluded.  Read my comment again.  I think women who use NFP and find value in their marriages and in their lives from doing so have their own story to tell, a viewpoint that also needs to be talked about and shared.  But it is a minority viewpoint for most women, including Catholic women, in countries where contraceptives are widely and easily available.  What should not be ignored any longer is the huge majority of Catholic women and their Catholic husbands who do not accept NFP as a reasonable method for managing family size, the timing of children, and even assuring the health of the woman.
