I suppose if the play were about a young girl being raped in an alley, that wouldn't be offensive? So desecrating the temple is more offensive than raping the young girl?

Unless the play actively encourages people to hate Sikhs, or portrays them collectively as bad people, what is there to be offended about?

And I dare say most Sikhs in this country have no interest in the matter, just as most Christians weren't campaigning against the equally "offensive" Monty Python, the Life of Brian a few decades ago.

I'm annoyed at the producers of the Archers introducing a storyline about a psychopathic rapist - especially at this time of year (which is stressful enough!) - so I won't listen to it again until I think the story line's over - but I uphold their right to broadcast it, even though I think it's unpleasant and in bad taste.
