There is an ominous increasing trend of aggression from Khalistani activists in recent times:
Along with this has come incidents like some Sikhs protesting alleged burning of Sikh holy books:
To me, this is reminiscent of the frequent Pakistani game of accusing someone of burning the Koran, as a thinly-veiled pretext to incite mob violence against them. Khalistanis are increasingly resorting to more and more aggressive activism, looking for opportunities to stoke up outrage. There is no precedent of any Hindus disrespecting holy texts like Guru Granth Sahib - but that won't stop the Khalistan brigade from raising the cry of "Sikhism in danger" in the same style of Islamists. After all, it was Pakistan which helped to set Punjab on fire in the first place, in order to use it to set Kashmir on fire. The ISI may now be working overtime to make history repeat itself.
India needs to be vigilant against anyone trying to create another Bluestar situation, or similar prtext for outrage.
