It's a lot easier to reflect on issues of "family planning" and "contraceptive methods" from the vantage point of "no dog in the hunt." I’m too old for the issue to affect me personally. I have the luxury of gazing back over my life and recognizing "the follies and selfishness of youth" – and, regrettably, I have a checkered past from which to speak.
My point in raising this issue at all is to "reveal" that there can be and is a lot of selfishness present in any form of "intention" against children. Teaching couples to use NFP without addressing the "serious reasons" and the idea of "generous" parenthood seems negligent to me.
