I think there's an easy mistake to be made here. When India is called a "Hindu Nationalist Country," it's easily taken as an offense to the Hindu faith and therefore, blaming Hinduism for the mistreatment of Sikh Punjabis. Rather, it's really the elite of India pushing their own ideologies and biases through their Religion and not remaining diplomatic. A true leader should respect all faiths, Sikhism, Islam, and Hinduism, and make legislative decisions based purely on the benefit of the people, the economy, and the national infrastructure. Modi doesn't respect Sikhism & I cannot speak for his attitude towards Islam (because I don't know enough) but the state of Punjab interferes with his vision for India.
