First of all,there is absolutely no proof that this movie or it's contents were the reason for these blasts.Far more provocative movies directly based on religion have been made in India & nothing of this sort has happened.Sikh terrorism has virtually been non-existent in India for 15 years & it's survives(on a ventilator) in North America & Britain.On the other hand,some nice folks may have just wanted to use this as an alibi to blow up an Indian or 2 given that things haven't been going well for them with Indian security measures in Kashmir or American pressure on n Pakistan.
Oh, I see, they are unhappy with America so they blow up some theaters and plant a bomb on their railway... it's our fault again, right?
