How is that a threat to India's sovereignty or security?
Modi is infamous for having caused, by his actions or inactions, the Gujarat riots that killed 2000+ people. Hell, he was even banned from entering the US, till he became the Indian PM. There is blood on his hands and lots of it.
And to give some context on this hash tag, I believe it came after the gov't put across barricades and barbed wires to caroll the protesters leading many to believe that the regime was planning a major crackdown. The situation in the first week of Feb was very tense.
