Stephen Ira, Warren Beatty's Transgender Son, Slams Chaz Bono As 'Misogynous' In Blog Posting

The transgender son of Warren Beatty and Annette Bening has lashed out at Chaz Bono on his blog, accusing the recently departed "Dancing with the Stars" contestant of being misogynous.

Nineteen-year-old Stephen Ira Beatty, who was born Kathlyn, accused Bono, 42, of being unqualified to speak about gender reassignment. "Chaz has appointed himself as the representative of a group of people who are not all like him," Stephen writes. "He has said misogynistic and prescriptivist things about gender. I take particular issue with his comments on trans embodiment and on women."

Stephen takes particular issue with Bono's assertion in The New York Times, in which he likened being transgender to having a birth defect. "There's a gender in your brain and a gender in your body. For 99 percent of people, those things are in alignment," Bono said in May. "For transgender people, they're mismatched. That's all it is. It's not complicated, it’s not a neurosis. It's a mix-up. It's a birth defect, like a cleft palate."

Stephen responded, "Chaz is a misogynist...This man doesn't represent our community. He especially does not represent those of us who are non-binary, non-op, women, or feminist men. Chaz needs to do some hard thinking about what it means to appoint oneself representative of a whole group without considering the desires of all the group's members."

He later followed the original post up with a second blog dated Nov. 17, presumably as an effort to clarify his views. "I would be more than happy to sit down with Chaz, have a drink, and talk with him about how he can think and talk about gender in a way that’s more inclusive," he wrote. "He seems like an all right guy, his questionable views aside. And from what I’ve seen, he’s really remarkably good at the cha cha."

Stephen, who is reportedly attending college as a man, was said in 2010 to be planning to undergo gender reassignment surgery. According to the National Enquirer, his famous father was "beside himself over the situation."
