I have had a lot to absorb from the film. The most important thing is every one of us is created to be a good human, and shamefully, the parents are usually the villains, who instill prejudices and hatred in their kids towards others. What a shame to poison their own children!
For Centuries, India has been a blessed nation where people of different faiths have interacted with each other, went to work and schools together, and they see the movies together and attend funerals, weddings and other ceremonies.
However, there is a trend of separation growing and it must be curbed, before it is too late. There is a problem is with the teaching; the kids are raised in seclusion and limited knowledge about each other, and whatever little they know about the other is negative. In the long run it breeds more conflicts and tensions for all. One cannot prosper and live in peace when others around him are not.
A true patriotic Indian would considers every Indian his larger family, same goes to Pakistan or any other nation. Once we start denying the otherness of others to others, arrogance creeps in and we start feeling we are somehow better than the other. Damn us for such arrogance, that is what kills the society and relationship, all of us are going to die one day and will either be buried or cremated, we are done with you, no matter who you are. I hope you felt agitated with this paragraph, and I am glad you did, make an effort to treat every one as equal and see the sense of serenity you feel inside.
When the Imam drops the hero to a safer place in Pakistan, the hero had difficulty in saying Khuda Hafiz, whereas the Imam goes ahead and says Jai Shree Ram to him – causing him to think about his own bias – by saying Khuda Hafiz he does not become a Muslim, it is merely a word to communicate good wishes of safety. It’s my dream to see a day, when people greet each other with Namaste, Salaam, Shalom, Jai Jinendra, Satsri akaal or other phrases as synonyms. There are many videos about it; here is one that I did in front of a thousand audiences in a Chicago Bible college in a seminar. https://www.youtube.com/watch?v=Eo3a8wX6SXQ . When the girl says Jai Shree Ram at the end, it is a beautiful expression of good wishes.
Again, a majority of all people are good people, as witnessed in the movie, people will come around for goodness, goodness is natural to us and we gravitate towards it. If you don't, forgive your parents for making you bias, and get out of it and enjoy the freedom without prejudice.
