Whether we like it or not, the basis of division of land was religion. That was the deal. We got a raw deal. Having said that, we should respect all muslims who are truely Indian, follow family planning, are willing to accept uniform civil code and do not celebrate when Pakistan defeat India in cricket.
Also, I fail to understand how India would have become chaotic if we were a non-muslim country ? There would be uniform civil code and no-minority appeasement. NDA and UPA would have to fight elections on true issues rather an Religion/Caste etc. Religious parties like BJP would not exist.
