Apart from the rise of the BJP, one other factor that has facilitated this fervent flag waving is the Supreme Court order delivered on January 23, 2004 (Union of India versus Naveen Jindal) that ruled all citizens had the fundamental right to fly the national flag. Khare, carefully weighed the arguments for and against lifting the restrictions imposed till then on flying the national flag. Pointing out that the "National Anthem, National Flag and National Song are secular symbols of the nationhood," it said that even though not explicitly stated in the Constitution, flying of the national flag "may be held to be a part of the fundamental right". It is common to see macho men on motorcycles holding aloft the national flag while shouting provocative slogans. Flag waving is perhaps the least of them - and threatens to become the most pernicious too.
