What aspect of Lilliputian society does Gulliver find most absurd?

Gulliver finds the Lilliputian legal disputes over trivial matters to be the most absurd aspect of their society. This reflects the overarching theme in "Gulliver's Travels" of how societal norms and practices can appear ridiculous when viewed from an outsider's perspective. The Lilliputians engage in lengthy and complex legal battles over seemingly insignificant issues, which underscores the satire in Swift's description of human nature and governance. Their preoccupation with minor disputes highlights the ridiculousness of prioritizing such trivialities while larger, more pressing issues remain unaddressed. This critique serves as a commentary on the absurdity of excessive bureaucracy and the often petty nature of political conflicts in any society. In contrast, the other aspects such as their size, education system, or culinary preferences, while they may seem peculiar, do not embody the same level of irony and critique as their obsession with trivial legal matters.
