Warren Beatty and Annette Bening’s transgender son Stephen Ira, born Kathlyn, blasted Cher’s transgender son Chaz Bono, born Chastity, calling the ex-“Dancing With the Stars” contestant “a misogynist who does not represent us.” In a blog post, Ira rails against Bono for saying that transgenderism is “a birth defect, like a cleft palate,” and that “being male and having breasts is about the worst thing I could imagine.” Ira also attacked Chaz for saying, “I never understood women before . . . but I had a tolerance for women that I don’t have now . . . There is something in testosterone that makes talking and gossiping really grating.” Ira, who admitted to undergoing hormonal treatment, responded, “I don’t want any rich white trans guy . . . telling the media that testosterone made him a misogynist . . . he has some deep-seated misogyny to work through.” Ira, who’s at Sarah Lawrence, also vented about the school’s refusal to accept his new name. He calls himself “a transsexual who refuses to be treated as a logistical problem.” Bono’s rep declined to comment.
