Hunger Or Love?

We can immediately see we often confuse the two. Someone will say, 'I love chocolate,' but that will be perfectly okay because we all know she really meant to say she desires chocolates and likes to consume it. The more important distinctions come later.
If we look a the major foods we consume, we can see we are very good at making the foods we enjoy abundant. There is plenty of corn, wheat, and the like. We really like to eat steak and drink milk, so there are plenty of cows in the world. Endangered species usually aren't on the menu- if they were, we'd figure out a way to grow more of them.
Now, perhaps some inattentive alien, passing by this planet might assume we love cows, for there are many of them, and most of them live a pretty good life- at least they probably think they do. But we give them such a good life out of enlightened self-interest- we are not trying to figure out what is in the cow's best interest, rather we are trying to make meat. So we control their breeding through a variety of measures, including castrating untold number of steers. We keep dairy cows producing milk for as long as possible. We feed cows a diet design to maximize meat, not for longevity.
Now turn for a moment and think of relationships with humans. Love requires giving what is good to the other person, and yet we see the great confusion of same-sex partners and other deviant behavior, for clearly there are parts of those relationships that seem loving. But it is the affection of hunger, not love. A person in love would seek the best for his beloved, and even the most dedicated atheist ought to notice that becoming an evolutionary dead end isn't beneficial. However, children are a responsibility that can take valuable time away from sin.
We can see why, in the Old Testament, David and Jonathan may have loved one another very much, but they never once thought of deviancy as a way to express that love, because to do such a thing would be to destroy rather than build up.
In love, the other person's well-being determines how we relate to the other person, and we limit the expression of any desires we might have as is appropriate. In hunger, our self-interest determines how we shall respond, and we may respond quite affectionately, if that is the way to sustain and satisfy our desire.

Sadly, some never learn this distinction and are forever finding themselves trapped in predatory relationships (whether they are the predator, prey, or both) when they are in fact seeking loving relationships.
