Tesla and SpaceX CEO Elon Musk has once again found himself at the centre of a social media storm after making a controversial statement about womanhood on X, the platform he owns. Musk claimed that being a woman is defined purely by biology — specifically, the presence of a womb — a remark that quickly went viral and drew sharp reactions online.
Correct. We’re sorry your daughter hates you, Elon. https://t.co/HeJIm5fJMS

“If you have a womb, you are a woman. Otherwise, you are not,” Musk wrote in a post on X.
Within hours, the statement triggered an intense debate, with users split between those supporting Musk’s biological definition of sex and others criticising it as inaccurate and exclusionary.
Supporters rallied behind Musk, arguing that biological facts are being unnecessarily politicised. One user commented that they “can’t believe we’re living in a time where the obvious has to be stated,” to which Musk replied, “Seriously.” Another supporter said the episode reflected a bizarre moment in history, where what they described as “basic biology” had become controversial even among educated people, suggesting the exchange deserved to be “pinned on the timeline of humanity.”
However, critics pushed back strongly. One user pointed out that Musk’s claim ignores medical realities such as MRKH syndrome (Mayer-Rokitansky-Küster-Hauser syndrome) — a rare congenital condition in which women are born without a uterus or with an underdeveloped one. Critics argued that such examples undermine the idea that the presence of a womb alone can define womanhood.
If you have a womb, you are a woman.

Otherwise, you are not.
Context: Musk’s Ongoing Criticism of Gender Transition
The controversy comes just a day after Musk made remarks comparing his transgender daughter’s transition to what he described as a “tragic mental illness.” The comment was posted in response to a jibe from a Democratic politician directed at the world’s richest man and further highlighted Musk’s outspoken opposition to gender reassignment and transgender-related policies.
The exchange also followed remarks by California Governor Gavin Newsom, who said during a podcast appearance that he wanted to see more trans children, portraying himself as a strong advocate of pro-trans legislation and LGBTQ rights.
Newsom’s office later reposted a clip from the interview with a pointed caption aimed at Musk:
“We’re sorry your daughter hates you, Elon.”
A Debate That Continues to Divide Social Media
Musk’s comments have once again brought discussions around gender identity, biology, and transgender rights to the forefront, underscoring the deep cultural and political divides surrounding the issue. While his supporters argue that biological definitions are being eroded, critics say such statements oversimplify complex medical and social realities.
As the post continues to circulate widely, the backlash and debate show little sign of slowing down.
