When ideology clashes with reality

Gay rights activists are outraged at a gay actress because she says she chose to be gay.  The LA Times reports:

Former “Sex and the City” star Cynthia Nixon says she is gay by “choice” – a statement that has riled many gay rights activitists who insist that people don’t choose their sexual orientation.

Here’s what Nixon, who recently shaved her head to play a cancer patient in a Broadway production of “Wit,” told the New York Times Magazine:

“I gave a speech recently, an empowerment speech to a gay audience, and it included the line ‘I’ve been straight and I’ve been gay, and gay is better.’ And they tried to get me to change it, because they said it implies that homosexuality can be a choice. And for me, it is a choice. I understand that for many people it’s not, but for me it’s a choice, and you don’t get to define my gayness for me.”

It seems to me that gay activists have unnecessarily backed themselves into a corner over this. The case for gay rights should not depend on a claimed lack-of-choice.
