Now it has been scientifically proven that the Aryan Invasion Theory fabricated by 19th century Indologists is totally false. Aryan is not a race at all. Anyone who lives per the Vedic dharma to advance spiritually is an Arya. The homeland of the Vedic Dharma and culture is Bhaarat (Aryavart).

Islam in Bhaarat, in contrast, has invaded by force, and no invader has right to be in the invaded country. Therefore, the Aryans (the Hindus) must purge out Islam from the Deva Bhuumi Hindustan.
