It seems you don't know the history of the founder of your own country. Mr Jinnah was a secular nationalist in the mould of his mentors Dadabhai Nauroji, a Parsee, and Gopal Krishna Gokhale, a liberal Hindu Brahmin. The main reasons Mr Jinnah left the Congress were because, under Mr Gandhi , the Congress abandoaned its emphasis on constitutional methods and because it started to appeal to religious issues to mobilize the masses. Mr Gandhi was instrumental in Congress taking up the slogan of "Ram Rajya" and supportering the maulanas in the Khilafat movement - a move Mr Jinnah opposed because he correctly anticipated would unleash religious zealotry that could not be controlled and because he wanted to look forward like Ataturk in Turkey and not backwards.
I hope you know most of the ulema in undivided India opposed the creation of Pakistan and labelled Mr Jinnah Kafir e Azam. In Mr Jinnah's vision, Pakistan was created as a homeland for the subcontinent's Muslims because he feared that under a democratic government the Congress would have a permanent majority and the political and economic rights of Muslims would be suppressed. Till the end, he tried to find a compromise which would enshire constitutional guarantees protrctiing political and economic rights for Muslims in an undivided India. However, the Congress leadership, with the exception of Mr Gandhi, and Mr Mountbatten believed giving in to Mr Jinnah's demands would result in a very fragile state and ultimately Mr Jinnah was left with no option but to accept what he himself described as a "moth eaten" Pakistan. Mr Gandhi was bitterly opposed to partition and tried to offer concessions including making Mr Jinnah the Prime Minister of undivided India to avoid takseem e hind , but he was isolated within the Congress. The irony is that while Mr Gandhi and Mr Jinnah are both considered fathers of their nations, neither of the countries they created ended up adopting the visions their fathers had.
It was the Pakistani army that committed genocide starting with Operation Searchlight. Are you trying to say Yahya, Tikka Khan and Niazi were operating under the orders of some Brahmins? Mujib had been democratically elected Prime Minister of undivided Pakistan. He had no reason to resort to any violence because he would have become the legitimately elected ruler of undivided Pakistan anyway.
