It is not true that Jadavpur University did not implement OBC reservation. In faculty of arts and science this rule has been implemented 100%.
I seriously don't understand the need of giving reservations to the Muslims. It was the Hindus of East Bengal who were at the receiving end of the riots and killings that ensued the partition. But is reservation given to them? Why does it appear to you that the only metric of social justice is how much reservation is given? Muslims of West Bengal are thriving.
