The Satanic Temple supports it’s trans members using the same basis as it’s stance on abortion. There are 7 fundamental tenets of Satanism. The third states that “One’s body is inviolable, subject to one’s own will alone.” and the fifth is “Beliefs should conform to one’s best scientific understanding of the world. One should take care never to distort scientific facts to fit one’s beliefs.” Based on these tenets it is the religious stance of TST that trans individuals have a fundamental religious right to decide what happens to their body and a religious obligation to reject unscientific claims and “treatments” with regard to their gender identity.
