In 1969, the Stonewall uprising took place in New York, which later led to a series of gay rights movements in the United States and across the globe. The gay rights movements have since made remarkable progress well into the 21st century. Currently there are at least 25 countries where same-sex marriage is legally performed and recognized, whilst Taiwan has become the first Asian country that declared any prohibition of same-sex marriage “unconstitutional” by the Grand Justices in 2017. By the end of the 20th century, Gay and Queer Theologies also emerged as part of Christianity that tried to defend LGBTI groups. Among these individuals, however, the “intersex” people (which stands for the ‘I’ of “LGBTI”) have been long trivialized or even dismissed by the aforementioned theologies. The aim of this paper was to comb through the literature in western gender studies, and proffer criticisms for the “gender binary based” heteronormativity presented by Karl Barth, a reformed theologian who was an advocate of Gender Theology and gender binary of traditional Christianity. Ultimately this paper makes a heroic effort to prove the theological fallacies firmly held by those anti-LGBTI Christians, and then present an even more radical Queer Theology for readers to ponder
