It may be possible to write a persuasive essay about the need to feed all the hungry children in the world, but it would not be a particularly interesting essay because no reasonable person would declare that all the hungry children deserve to starve. It might be more interesting to try to persuade readers that half of all American tax dollars should be earmarked to go first to all the hungry children of the world; you will probably uncover at least one or two dissenting viewpoints. Conversely, you might suggest that it is wrong to spend American tax dollars this way, and that the hungry children should be taken care of entirely by rich private donors; again, in this you will find a difference of opinion among reasonable people.
