This is certainly a subversive movement. More than anything else its approach and objectives are undemocratic. The issue being discussed is not Shiv Sena or other organizations but SIMI. Two wrongs don't make a right. Also when the highest court in the country (which by the way is one of the pillars of democracy) has said that SIMI is a secessionist organization who are we to question its erudite judgement.
