You are way of the mark. Look at the histry of Hyderabad and Ahemedabad Communal voilance ( leaving 2002). They all happened in Congress time. Congress is the creator of the Bindhranwale and then killed him. THey masacared 4000 Sikhs and Rajiv Gandhi shamelessly made posters of Dead Indira Gandhi and Durga Mata to win the 1984 elections.
BJP atleast honestly accepts that they care for the welfare of all including Majority and Minority
