Why tongues of traitors hailing Pakistan should not be chopped

Senior BJP leader Kailash Vijayvargiya today stoked a new controversy by wondering why tongues of traitors who "hail" Pakistan while living in India should not be "chopped off."
"Should not the tongues of those traitors who hail Pakistan while living in India be chopped off?" he asked in a series of tweets.
In the tweets, the BJP general secretary said an ex-serviceman asked him that soldiers stake their lives on the border while people inside the country "hail" Pakistan and nobody says them anything.
Referring to his conversation with the former soldier, he said, "Why tongues of such traitors who hail Pakistan while living in India are not chopped off? It seemed to me that the the former soldier was voicing the thought all patriotic Indians."

Vijarvargiya, however, also wondered if such a punishment was possible in a democratic country like India which follows constitutional practises.
Vijarvargiya's comments have earlier also kicked up controversies in the past.
