"In India, nationalism should be and is an inclusive and secular concept that allows people to participate in the processes of the nation without inhibitions and encumbrances.
In view of the raging political discourses in respect of nationalism it is imperative to disentangle communalism from nationalism," Thapar said at launch of a book, titled 'Communalism is Post Colonial India: Changing Contours'.
"Nationalism is not a category of exclusion but an enabling agency that doesn't differentiate on the basis of identities of religion and cast.
Thapar said India needs to re-construct the definition of nationalism that is "secular, inclusive and democratic".
