A government's first and foremost duty towards its citizens is to provide a secure and stable social environment in which they can freely carry out the 'pursuit of happiness'. The recent incidents in Mumbai and Mangalore have proved that both state governments have failed in this respect.
Rule of law as a basic principle of governance has to be upheld by any government, otherwise that particular government loses its moral right to govern. If a government can not govern according to the laws in force, it should either resign or be brought down. No political party should be allowed the temerity of indulging in selective governance. If you can not uphold the constitutionally guaranteed basic human rights of citizens regardless of their gender, religion, preferences or beliefs, you have no right to govern.
Hooliganism and vigilante culture if tolerated by society, carries with it the risk of destroying society's pluralistic nature and its tolerance of alternate lifestyles or points of view. This would lead to the distorted extremist beliefs espoused by a few to dominate society and culture. Talibanisation is not too strong a word to describe this phenomenon.
What is even more worrying is that the victims are afraid of speaking out fearing reprisals. That shows the degree of faith they have in the state apparatus to protect them. All of us who want our society to retain its pluralistic nature, have to raise our voices so that the governments in question are forced to make such hooligans face the full fury of the law and not get away with a slap on their wrist.
