His comments come in the backdrop of a raging debate on freedom of expression after an event against the hanging of Parliament attack convict Afzal Guru was held at the Jawaharlal Nehru University campus where anti-national slogans were allegedly raised.
Earlier Dhoni’s teammate Shikhar Dhawan had supported Union Government's move to hoist national flag on the campuses of all 46 Central Universities in order to instill nationalism and pride in students.
