If jinnah was secular, then advani would have preached secular politics in Sind rather than practising the same in India. Remember that pakistan's ideology is based on anti India and anti-hindu hatred. The day pakistanis feel that there is nothing between a hindu and a muslim, that day will be the last day of pakistan. the pakistani establishment will have none of it and hence the repeated whipping up of anti hindu and anti india sentiments. The muslim league toadies in 1940's were the stooges of the british and were encouraged to break indian unity at any cost.if jinnah had not done it, then somebody else would have done it. hence dont bring the theory that pakis were secular.
