Omlettes - It seems plausible that the Taiwanese boxer has a VSD and that was not an area that the survey evaluated, afaict.
Gender self-identification (transgender) is not permitted in most Asian countries. In Taiwan, individuals recognized as transgender must meet requirements mandated by the Gender Recognition Act. Currently, lifting the requirement for proof of sex-reassignment surgery is pending. The aim of this study was to survey a large sample of Taiwanese to gain a better understanding of the general population’s attitudes toward gender self-identification… Although there were significant differences in scores between parents and non-parents, and those ≤ 35 years versus ≥ 36 years (p < .01), all strongly disagreed with gender self-identification. Given the majority of respondents were females, survey findings should be regarded with caution. Public acceptance of gender self-identification requires support from its residents. Our findings suggest that gender self-identification has not begun to approach even a moderate level of public support among survey respondents.
