The sort of extremism that led to the lynching of a 55-year-old dairy farmer in Rajasthan's Alwar district last week is not very different from the brand of fanaticism endorsed by ISIS, economist Surjit Bhalla said on The NDTV Dialogues. "Nobody is for this kind of nonsense. The cow slaughter vigilantism is ISIS in India there is no difference... No sane person can defend or support or even offer excuses for what is done in the name of a cow. It is just horrible," Dr Bhalla said.
