From the Sydney Opera House Facebook page:
The Festival of Dangerous Ideas is intended to be a provocation to thought and discussion, rather than simply a provocation. It is always a matter of balance and judgement, and in this case a line has been crossed. Accordingly, we have decided not to proceed with the scheduled session with Uthman Badar. It is clear from the public reaction that the title has given the wrong impression of what Mr Badar intended to discuss. Neither Mr Badar, the St James Ethics Centre, nor Sydney Opera House in any way advocates honour killings or condones any form of violence against women.
What else was he going to talk about?
Update: Simon Longstaff takes to twitter:
The session to explore 'honour killing' has been cancelled. Alas, people read the session title – and no further. Just too dangerous.
