I personally think we can still have Durga Puja but as long as we limit ourselves to celebrate around our own areas like we already do during Kali Pujas and Diwali.
This is spirit of my state Assam. Some guy of world peacemaking religion shows up and burns religious books at one of our holy sites completely unprovoked. What locals did was catch the guy, gave him what he had coming and hand him over to cops. There was no burning of property, no riots. This is how to deal with peace lovers.
