Elon Musk Says Womb Defines Womanhood After Calling Trans Daughter 'My Son' With 'Mental Illness'
Musk's online comments revive scrutiny of his estranged family relationship

Elon Musk has ignited renewed controversy after declaring that womanhood is defined by biology, a remark that has intensified scrutiny of his strained relationship with his transgender daughter and fuelled a broader debate over gender identity in the United States. The billionaire technology executive's comments, posted on his social media platform X, have prompted strong reactions from politicians, activists and members of the public, underscoring how his personal views continue to reverberate far beyond Silicon Valley.
Musk wrote that 'if you have a womb, you are a woman', a statement that critics say excludes transgender women and reduces gender identity to reproductive anatomy. Supporters, however, argue that he is expressing a biological definition of sex. The post quickly gained traction online, drawing millions of views and thousands of responses within hours, reflecting the polarised nature of the debate.
The comments arrived amid renewed attention on Musk's remarks about his transgender daughter, Vivian Jenna Wilson. In recent exchanges on X, Musk referred to her as his 'son' and described her transition as a 'mental illness', language that has been widely condemned by LGBTQ+ advocacy groups as stigmatising and harmful. Musk has previously claimed that he was misled about aspects of his child's transition, an assertion that has also been challenged by critics.
If you have a womb, you are a woman.

Otherwise, you are not.
Musk's Comments on Gender and Family Under Scrutiny
Vivian Jenna Wilson, born in 2004 to Musk and his first wife, author Justine Wilson, came out as transgender several years ago. In 2022, she legally changed her name and gender marker and requested to sever ties with her father's surname, citing a desire to distance herself from him. Court documents from the time indicated that she did not wish to be related to Musk 'in any way, shape or form'.
The relationship between father and daughter has remained publicly strained. Vivian has spoken about feeling unsupported during her transition, while Musk has repeatedly voiced opposition to aspects of transgender healthcare for minors and criticised what he calls 'woke ideology'. His latest comments have once again placed his family life at the centre of a global conversation.
The controversy escalated further after an online exchange involving California Governor Gavin Newsom. Newsom's office posted a message referencing Musk's daughter, which Musk responded to by reiterating his previous remarks. The ongoing argument attracted the attention of various public personalities and commentators, thus making the confrontation a political flashpoint.
Musk's statements are seen as a part of a larger issue by LGBTQ+ organisations. According to the advocacy groups, it is only the existing bias that will be supported and the misguided information that will be disseminated by portraying transgender identity as a mental illness. Furthermore, they have pointed out the American Psychiatric Association's and other well-known medical bodies' viewpoint, which does not classify being transgender as a mental disorder, as one of the justifications for their claim.

Political Fallout and the Wider US Debate
Musk's remarks about womanhood come at a time when the issue of gender identity is very much alive and debated in US politics. Several states have introduced or approved bills which affect transgender individuals in their healthcare choices, participating in sports, and accessing public spaces. Thus, a person like Musk can have a great influence and make a major difference in the public discussion.
Musk, being the owner of X and the CEO of major companies like Tesla and SpaceX, has a huge online following. His posts are often a mixture of personal opinion and comment on the cultural and political issues of the day, and they frequently lead to controversy. He is praised by supporters for his challenging of the existing narratives, while he is branded by critics as a purveyor of harmful rhetoric.
The response to his last comments has been predictable. There were some users who were in agreement with him and put forth the biological definition of womanhood as a justification of their stance by calling it an argument for science and free speech. On the contrary, there were others who charged that he had shut his eyes to the realities of the transgender people's lives and was using his powerful waving to legitimise the views of the exclusionists.
Musk, nonetheless, has continued his line of communication in the same controversial fashion even after advocacy groups and some politicians have called for more responsible language repeatedly. On the contrary, the episode has made him even sturdier at the centre of the debate over gender identity, free speech, and the responsibilities tied to the immense public influence in the US that is still ongoing.
