Asked about "Love Jihad", a term currently in wide circulation in the BJP and its allied groups, Home Minister Rajnath Singh today said: "What is that? I need to understand its definition."br br Mr Singh's response raised eyebrows a day after his party MP Yogi Adityanath, a combative voice against "Love Jihad" and the BJP's star campaigner for by-elections tomorrow in Uttar Pradesh, was reprimanded by the Election Commission for a hate speech.br br Adityanath, a four-time BJP MP from Gorakhpur, has described as doctored a video in which he purportedly asks supporters to convert 100 Muslim women through marriage every time a Muslim man marries a Hindu.
