Why do you view the world in black and white?
I don’t view the world in black and white. What I view in black and white is morality.
Acts which humans perform can be things which are simply acts we perform as animals. We sense. We eat. We sleep. We blink. We scratch itches. We move about. Those are not acts which have any sort of moral component.
When we use our intellect and will, however, we are performing a moral act. And all moral acts are either good or evil. They must be, based on how moral acts are defined.
A moral act is one which consists of an object (what is done) and an intent (what we have in mind when doing the object). If both the object and intent are good, then the act is good. If either or both are evil, then the act is evil. Circumstances can make a good act more or less good, or an evil act more or less evil, but can’t make good into evil or evil into good.
If an act with a good object (I give to the poor) has an evil intent (I want to be seen doing it so others will praise me for being so wonderful), then I have done evil. The fact that the object results in a poor person receiving a benefit does not justify having an objectively evil intent. If it did, then the means would justify the end and any evil intent could be excused by claiming a good object.
If an act with an evil object (stealing food from the grocery store) has a good intent (I want to feed my family), then I have done evil. The fact that one of the circumstances may be I am out of work and my family is starving does not justify doing something objectively evil. If it was permitted to do evil with the intent that good come from it, then the end would justify the means and any evil object could be excused by claiming a good intent.
Many contracepting couples have a good intent. There’s nothing wrong with avoiding pregnancy for a time if the reasons are just. However, a good intent does not a good object make. The object must be good in and of itself for the act to be good, and contraception is not a good object. It divides the unitive and procreative purposes of sex. That division, over time, has negative consequences for society at large.
In 1968, Pope Paul VI talked about some of those negative consequences in the encyclical Humanae Vitae. In the past 40+ years, we’ve seen his predictions come true.
But, as I’ve said before, when a negative consequence is not clearly self-evident then we can always come up with excuses for our actions. And the negative consequences of widespread use of contraception are not clearly self-evident. If you do not want to be convinced, then I’m afraid no one can convince you.
I am not here to be convinced or not. I am simply interested in the types of arguments that are brought up. Of course we can always declare a stalemate, and part on amicable terms.
You appear to be professing a detached academic interest. But that’s at odds with your behavior in this thread, which has been active defense of a specific argument.
