I will answer your querry only for the purpose of debate and information. I will not indulge in any mudslinging.
In my view the arguments put forward by the religious parties of undivided India were based on logical conclusions based on the prevailing situation of the times. You need to understand that just as Mr Nehru changed his stance , in some ways the mullahs also realized the problems to be faced by the muslims in india, and became a part of the movement.
Their objections were as follows:
1)If Pakistan is being demanded in the name of Islam, a natural consequence of this is so that the muslims could lie their lives as muslims in an Islamic state. The leadership of the time(Quaid e Azam Mohammad Ali Jinnah and the muslijm League) do not know the ABC of islam . So how are they going to establish an Islamic state. If on the other hand we want a democracy, what do we gain by dividing the muslims into 2 groups (ie India and Pakistan) when as minority in thew countryforming about 40% of the population and probably casting a block vate, they will alwyas be a power to reckon with in Undivided India.
2) the solution to the division required Pakistan to be formed of Areas of muslim Majority. Most of the literate muslims of India(with the exception Of Lahore ) resided i n areas which were not to form a part of pakistan. In the case of such a division, what will happen to these muslims who may face the wrath of the Hindu population when their numbers would be depleted.
As you can see the arguments were sound and Mr Jinnah did not have any answer to the querry. To be fair even Mr jinnah till 36-37 was hoping for some form of autonomy for Muslims within the frame work of a combined India. it was only the vibes that he got from nehru, that made him realize that this was not going to be possible, and muslims will remain second class citizens in undivided india( an impression whether true or not i still do not know)that made him change his mind. The Mullahs reached the same conclusions and to be fair the support of the muslims from the minority areas of undivided india was instrumental in gaining momentum towards the formation of pakistan. Second factor , which no one knew at the time was Mr jinnah's own health condition which was deteriorating rapidly. he probably realized that without him Muslim league would flounder. This led to a certain urgency on his part and probably left a few loose ends which have festered and led to conflicts with in the region.
