Zippy At His Best

On the morality of contraception vs the morality of natural family planning:

A contracepted sexual act combines in one and the same behavior the pursuit of physical sexual satisfaction and a rejection of children.
---
But when it comes to the marital act, there is no positive duty for a couple to engage in it at particular places and times, where if they choose not to engage in it that choice not to do so is evil. If the couple decides not to get it on on the kitchen floor right here and now, that decision does not inherently by its very nature express hatred of children; else every moment the couple was not engaged in the marital act would be an expression of hatred of children.

When Zippy is good, he is very very good.
(When he's bad, he's usually talking about economics.)
