Your slogans ("all Indians are my brothers and sisters") are very nice, but bear no relation to reality. This is exactly what Kashmir's Hindus used to say until the Muslims started exterminating them with the slogan "Hindus must leave Kashmir, but leave your women behind". Wake up and smell the coffee.
While you are worried about the idealized past, the Muslims have a very clear picture about your future: one in which everybody on earth is a Muslim. They are working hard to make this happen. Similarly, Christians are working hard to make everybody on earth a Christian. If you are happy to be converted by force or coercion, that's your choice. If others protest, that's their choice, which you have to accept. The blood-letting is happening in the name of Islam everywhere that it exists: scholars talk about "the bloody borders of Islam". Individual Muslims are often nice and good people, but their mob mentality breeds violence at the drop of a hat. The cry "Islam is in danger" causes them to become mindless fanatics.
