Quoted a link to judge the number of violent incidents (mass murders or terrorist attacks ) are much less in Bihar or up than to gujrat , Kashmir , Punjab or Mumbai
I already explained about Mumbai .
Look at the above post.Kashmir ,you know the reason.Gujarat AFAIK not a single riot didnt happen after 2002.
Punjab .I dont even heard.
You dont know anything about UP and Bihar and casteism in there.That is why you said this.
