Kabir Khan made the best point so far in the 3rd video (2mins into it) that he wishes religion was something that we could all choose when we're 21 and that we're all merely born into our religions.

btw I'm sorry to say but dispite some of the nice things that Shahrukh is saying about Islam, he also admits that he knows very little about Islam at the same time. Zakir Naik is probably thinking "astaghfirullah" to everything that Shahrukh is saying, especially in regards to the religious upbringing of his kids.
Shahrukh Khan is simply a God conscience individual. There is hardly any "Muslim-ness" in him though.
I hope he realises that the only reason why he has become such a big movie megastar is
dispite Islam. He wouldn't have become what he has by reading the Quran every day, avoiding music or singing or dancing, praying namaz 5 times a day, segregating himself from the opposite sex (ie all those Bollywood actresses) etc.
It is all because he is living in a majority non-Muslim country and because he had such an irreligous upbringing (which he is very open about).
