Muslims have never become a part of mainstream India becuase they never want to become one. Sindhis from Pakistan & Parsis from Iran came to India and are now very much a part of Indian social fabric but the muslims have always kept themselves aloof. I do not blame common muslims for that. The problems lies in the Madrassas where the fanatic mullahs preach that Islam is the only religion and believers of other religions are "KAFIRS" India is an inclusive society and will welcome anyone who wants to be included in it. But if you just want to remain outside no one can help. I agree that all muslims are not terrorists but then all terrorists behind these henious crimes are muslims. This requires some thinking.
