These people you quote did not become great because of religion. They became great because they considered religion to be a private thing and did not use the way you are. You last statement "our religion is based on truth and not yours" gives you away. Thank of all or any great muslim indians like the ones you name above and imagine would they ever make such a statement? And imagine what would they say when you say this in front of them? If you can do this without jumping out of your skin to type a reply, you would understand what makes them great.
