The word cisgender was first coined in 1994 and entered into the dictionary in 2015 in response to growing conversations around gender identity. The word refers to a person whose gender identity corresponds to their sex registered at birth.
Musk has previously stated that the word “cis” is deemed a slur on his platform X/Twitter that he acquired the social media site in 2022.
In June 2023, he wrote: “The words ‘cis’ or ‘cisgender’ are considered slurs on this platform.”
It seems the billionaire’s views have not changed after he recently claimed in another post that cis is “a heterophobic word”.
Musk claimed: “Cis is a heterophobic word. Shame on anyone who uses it.”
