The secularism of Javed Akhtar

The story related to the film Deewar written by Javed Akhtar is familiar. The hero of the film is a Hindu, an atheist who hates the Hindu religion so much that he doesn't set foot on even the stairs of the temple. He doesn't even touch God's prasad. But the same atheist Hindu hero, has an Islamic religious symbol, the number 786 billa on his arm which he deeply believes in! It's the same billa saves his life when a bullet hits him.
