This document discusses Taiwanese vulgar language and family views as reflected in Taiwanese kinship terms. It analyzes three categories of vulgar language and finds that insults involving sexual violence towards someone's mother are most malicious. Kinship terms and marriage customs show a patriarchal family structure where women join their husband's family. This and the value placed on male lineage help explain why mother insults are so offensive, reflecting Taiwanese concepts of proper bloodlines and gender roles where women's value lies in bearing sons. While changing language alone may not transform views, the document suggests introducing gender-neutral vulgar terms and educating on language and gender to help promote more equal perspectives.
