Disruption in PRD ceremony

why are we much influenced by communtal that ideas that we forget our basic ethics and rules.Creating a disruption in a ceremony where president of India was the chief guest is the height of indifferent thinking.

1.The Non Resident Indian
2.The Non returning Indian
3.The Non Reliable Indian
