I went to look something up regarding this squabble, and stumbled on this Time Magazine article from 1968 discussing Humanae Vitae: http://www.time.com/time/printout/0,8816,902263,00.html
Perhaps the bias will be sufficient to sicken even birth control proponents.
That said, this encyclical makes clear that those of you who support birth control don’t even understand the issue.
And that’s all I have to say about that.
Let me just state that you might try a slighly more persuasive and diplomatic tack to encourage those fundamentally disposed to disagree on this point. Saying that they/we cannot even understand will not help open ears to listen.
Second, I would find a different way of making your point than this article which makes it abundantly clear that a strong majority of the priesthood and of practicing Catholics could not understand the point either and that it created great dissention in the Church itself.
