On a sunny but chilly January morning, two days before Republic Day, thousands of people rallied across Mizoram in protest against the contentious citizenship (amendment) bill. Many of the protesters were carrying placards and banners that read, “Bye bye India. Hello China”. It was a radical statement by all accounts, a threat to secede from India. It’s the kind of statement issued by militant groups of the Northeast, not by the common man. Then again, this is not a common bill either. And this has brought together the people and political parties of the region against a common enemy—the “illegal immigrant”—leaving the BJP fighting growing alienation in a corner of the country it had found acceptance for the first time.
