From Wiki:
Although the party's primary base is still in Maharashtra, it has tried to expand to a pan-Indian base. In the 1970s, it gradually moved from solely advocating a pro-Marathi ideology, to one supporting a broader Hindu nationalist agenda, as it aligned itself with the Bharatiya Janata Party. It is commonly called an "extremist" and "chauvinist" party, as well as a "Hindu extremist" and fascist party
The group has been seen by some as a terror group, and has been linked directly with the 1970 communal violence in Bhiwandi, 1984 Bhiwandi riots, and violence in the 1992-1993 Bombay riots.
These claims are made by Indian origin analysts and political players. Its clear who is the brainwashed here
