The nature-versus-nurture debate was examined in a documentary last night (BBC1, 9pm) when John Barrowman tried to find out what made him gay. The programme summarised almost every theory about the cause of homosexuality. We saw John's delight when scientific tests confirmed that he was gay, and his satisfaction at the conclusion that sexual orientation is probably predetermined before birth and not willfully chosen.

The BBC online magazine includes a piece about John Barrowman's documentary. One reader wrote this comment:

Typical gay man, using his sexuality to boost his career. Lucky for some, my boss is female which means I can't follow suit.

And another wrote:

I am interested in why the BBC seems preoccupied with homosexuality or to be more precise it's promotion. Is it because according to Andrew Marr the BBC is disproportionately overrepresented by gays? And certainly in positions of influence to promote the gay agenda?
