Its a perfectly right step in the direction of highlighting the "dangers of terrorism to humanity" in general. Terrorists are the destroyers of humanity and find solace in some "comfortably lifted" religious quotes. Terrorism must be thwarted to let a society to live in peace, and the effort must be worldwide. Nothing wrong if Sadhus join the efforts against terrorism.
The most tolerant society is being tested for its tolerance, it will take only a short while when Hindus will join against terrorism to defeat it. Terrorism and its supporters must be wiped out of this world.
