No it was not Bharat but independent states not some union. Even if certain festivities were celebrated to the ends of the earth Allah put an end to it, right?
No! There are many differences in Hindu culture today according to different states. It is not one thing at all. Once again Islam is free of what the ancestors did as even the Prophet's ancestors were idolaters. I am glad my ancestors converted to Islam like did those from other countries as the truth of Islam convinced them ending falsehood. The Hindu God's could not change that or were happy to see it happen. You are right that being the truth Islam came last to correct other religions. Acknowledge what? I told you I don't give a damn what my ancestors believed. By "we" what is meant is Muslim's ruled over India.
Not really. There are still over a Billion Hindus in this world. 2 Billion Christians in this world and then a Billion Buddhists too. Not to forget millions of Sikhs, Jains, Jews etc.
