Activists angered by the banning of a documentary about same-sex parenting in schools have staged a protest outside the offices of Sydney's Daily Telegraph newspaper.

Around 150 people reportedly attended the rally, which was sparked by the controversial banning of the Gayby Baby film and the surrounding media coverage. Members of the group Community Action Against Homophobia have held a rally outside the newspaper’s Surry Hills office today to declare "homophobia has no place in schools".

The documentary was prohibited by NSW Education Minister Adrian Piccoli from being shown during class time, unless it directly relates to students' curriculum.

A number of teachers also attended and spoke at the rally in support of the cause. Read more via 9news
