The Guardian on the Sikh play

The Guardian interviews an actor in the Sikh play Behzti:

The violent protests that led to the closure of the controversial play Behzti
were the result of a failed attempt to work with Sikh community leaders, a
leading actor in the play has said.

The play was performed to community "representatives" and some changes were made. This appears to have given these members of the Sikh community the idea that they had a veto over the contents of the play, and ultimately over whether it was performed at all.

If the Birmingham rep took a clear free speech stand on the play, this might never have happened.
