Cynthia Nixon's comment on whether being gay is a choice were cited Tuesday in testimony against a gay marriage bill.

Testifying before Maryland's Senate Judicial Proceedings Committee against a bill that would make Maryland the seventh state to legalize gay marriage, Dr. Ruth Jacobs argued gay couples should be denied the right to marry because science has yet to determine whether sexual orientation is an immutable characteristic.

“I'm a physician. I practice in Montgomery County. Much of the testimony has revolved about [that] homosexuality is innate. The American Psychological Association has stated that no findings have emerged that have permitted scientists to conclude that sexual orientation is determined by any particular factor or factors,” Jacobs testified.

Jacobs then quoted Nixon's recent comments to The New York Times, in which the actress said that for her being gay is a choice.

“For her, being gay was conscious choice,” Jacobs said.

Nixon, however, has since expanded on her comments, adding that her bisexuality is not a choice, only her decision to be with a woman.

“I believe bisexuality is not a choice, it is a fact,” she said. “What I have 'chosen' is to be in a gay relationship.”
