Why does Swift focus on the benefits of his plan before giving us the details of it?

If you do not realize that this proposal is satirical, you have no sense of humor or irony. It is impossible to imagine a serious proposal for eating children. Yet, it is not enough simply to indulge one’s outrage over the argument or to smile at the jokes. Is Swift just having fun, or does he have something serious to say?

Stereotypes against Irish Catholics make it easier for Swift to use them as the subject of his satire. The stereotypes are present in both the reasons for the proposal and the language used. The narrator’s argument that something must be done with infants because they are too young to steal implies that this is a common employment of Irish Catholics, even while it is humorous apart from the stereotype. The overall idea of overpopulation comes from the stereotype that Catholics tend to have a lot of children. The first reason Swift’s narrator gives for adopting his proposal—that it will lessen the number of Catholics—is perhaps the best example of satire of religious prejudice in the piece. Furthermore, he uses the word “papists” in the offensive sense of anti-Catholic rejection of the Pope. In Protestant England, many people might share the stereotypes but would never go so far as the speaker suggests about eating children.This captures the imagination and "sensibilities" of the reader.
