What I read from many tweets is that Hindus of this country have been brainwashed with the idea that if the muslim population is not curbed, India will become a Islamist nation. This is the perception & they really believe in this falsehood! The sense of insecurity is so high that they think Indian muslims are the "invaders" and they have to protect their country from them. Also, Pak & Bang were India but invaded by these invaders. So they need to push out the muslim citizens to prevent further invasion.
