Gandhi’s Brahmin assassin was a former RSS activist.

Evidence

His assassin was Nathuram Godse, a Brahmin, and a former activist of the Hindu Mahasabha and the RSS. Godse was, if such a thing is possible, a most respectful assassin. First he saluted Gandhi for the work he had done to ‘awaken’ people, and then he shot him. After pulling the trigger, he stood his ground. He made no attempt to escape or to kill himself. In his book, Why I Assassinated Mahatma Gandhi, he said: [But] in India communal franchise, separate electorates and the like had already undermined the solidarity of the nation, more of such were in the offing and the sinister policy of communal favouritism was being pursued by the British with the utmost tenacity and without any scruple. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 173
