In that case you will have no trouble answering my question from the previous post, "Where in these articles is enunciated the essential Catholic principle that contraception is wrong because it violates the primary purpose of marriage?"
I presume this thread was posted to get people to think.
When someone is speaking about a grave topic of faith and morals, I would think that their purpose is to proclaim the truth. And certainly I assume that was CFA's purpose. One could simply "get people to think" about all sorts of topics, but it wouldn't necessarily be a good thing.
