In my view this is a very serious issue and hurts directly on our national integraty. Dont forget that VANDAMATRAM is our National Song and many of our freedom fighters in the past and defence force at present sing irrespective of their religion. When ever you sing National Song or National Antham you keep no religion or God or diety in mind. Its our country that we praise and worship in the song and not any particular religion or God.
If your hearts are pure and most importantly if you LOVE INDIA then their is no sin in Singing our National Song.
If you leave this issue tommrow they may say that praising \'BHARAT MATA\' (Mother India) is sin and is not allowed in our religion and so on and so forth.
