The solution from the hanging sword of Islam on India is very simple: Hindutva.
Pre-Eminent Indian Novelist Sarat Chadra Chatterjee , wrote in 1920s seeing futility of Gandhi's Muslim appeasement in the form of Khilafat Movement:
"Hindu Muslim Problem will be solved in a day, when Hindus become united by destroying their caste."
"Hindus have been trying to reconcile with Muslims for last 100 years and that is treated as Hindu-weakness. I would propose that Hindus stop this, and let Muslims take lead in Hindu-Muslim reconciliation for next 100 Years."
This is Hindutva. Only a United Hindu society can take on this growing menace of Islamists in India.
