Why communal riots happen?

It's cliched but true... Lack of sensible handling is just the sole cause of repeated occurance of communal riots in this country.. When the institution acts with political consideration, these are the results.. Most of the culprits of communal carnages are going unpunished... Anti-Sikh riots, Gujrath, Mumbai, Bheevandi, Maarad, Mangalore, Malegaon... the list goes endless.. only if the establishment acts without looking at the face, the communal brigades will stop erupting with mass hysteria... No one with some sense will jump into the act, if the fear of proper punishment would appear in his mind... Mindless authorities exploit every riot for political benefits... to encash the sensitivities of poor... Time and again, their acts encourage anti-social elements to comit crimes in disguise of communal passion... secularism should be practised.. not just preached... and secularism is not appeasement... it's the demonstration and practice of equdistance from every relegion and faith...
