I actually can't see it as an issue as those people are asking for "inclusion of jhatka" rather than "exclusion of halal". If muslims can boycott resturant for serving non halal meat and can ask for inclusion, why others can't request the same (their preference of killing animal)?
Why some muslims are taking it offensive way is hard to grasp. Though it does mention halal in the article, the demand has nothing to do with islam.
I dont think any Indian Muslims are taking an offence to it. Its the liberals in India, outraging over a legitimate concern being voiced by "some" Hindus. Their moronic braying, ends up making more people polarised on this issue. For once, they could be secular and ask for respecting all religious sensibilities.
