You are questioning about Indianness of a Muslim living in India. Take my own example, I am a one of them. Since my child most of my Hindu friends discriminated even though I never uttered a single word against India. When ever in Social Studies class if there is topic on India and Pakistan war, the whole class looks at me(I am only the muslim in the class) when teacher makes fun of Pakistan, dammit I am 9 years at that time for the Gods sake. Even after the class they call me traitor. After college I joined software job, here I am assumed that all my colleagues are grown up, educated and matured, I found some idiots there too, when ever there is cricket match between India and Pakistan and if Pakistan happen to win, they will come to me and congratulate and even one asked for the sweets. I will pity on all those guys who are asking to prove our Indianness.
First stop suspecting us because of few peoples actions. How come Killer Modi is still ruling a state, should I blame all Hindus for his actions. I believe mistake is both sides, right now solution is to unite and find the solution for terrorism and not blaming.
