Bargis is NOT equal to Marathas. Marathas had some Muslims in their army, does not mean those Muslims were Marathas. British had Marathas in their armies does not mean those Marathas were British.

Rise above your hatered. Stop this fake narrative. Not at all justifying what happened in Bengal, but twisting history to suit your narrative is wrong. Marathas were not named later by British or somebody else. Marathas were already known across India. Those people and lullaby could have easliy mentioned Maratha, instead of Bargis, but they didn't, because they were telling truth and not twisting facts.
