Congress leader Rahul Gandhi claimed BJP tries to erase the history, philosophy, medical science and lifestyle of Adivasis when they call them Vanvasis. "PM Modi says he will respect Dalits, tribals, and backward classes, but then he takes away their rights and expels them from institutions," he added. Rahul made these remarks during 'Samvidhan Samman Sammelan' event in Jharkhand's Ranchi.
