As a Pakistani Muslim living in Pakistan I don't have to face things like gaow rakhsha etc etc There are alot of religious freedom we have in Pakistan as a Muslim, which it seems Muslims in India do not enjoy.
However, counter argument to this is 220 million Pakistan, 200 million Bangladeshi and 250 million Indian Muslims comes to 670 million, which is more or less the majority or you can say not less than the hindus. So yes muslim power in India was weaken.
What would have happen, had their been no partition??? Well it might have resulted in Muslim rule in whole of India, or a very powerful muslim presences. It might have resulted in a civil war, massacre etc.
So in the end, i believe no one can predict who was right.
Partition is a reality now, so lets not debate on it. One thing I am clear about it is that undoing partition is not possible and will be the biggest disaster this world would have seen.
