The outspoken Basic Instinct star claims it's "absurd" Washington has been sent to therapy. She tells the New York Post, "'I've been called a bitch - and a lot worse - for years. And you know what, so what? People who think that aren't going to change their minds. "And I wouldn't dream of sending them to therapy to 'rehabilitate' their feelings. How absurd. "Please, I call all my gay friends 'big fags'." Washington has entered a 30-day anger management program in a bid to keep his Grey's Anatomy job.
