Religion is but a fleeting vantage point of our purpose on this planet. A tradition of folklore and historical events which we convey to our children to help them understand why they are born. Literature which we perpetuate for lack of a better understanding of the mysteries of this universe and out of fear of retribution and a prophesied Hellfire for failing to have done so.
No one person can prove their religion as no other person can disprove his. Let me help you remember that before we were Muslims, we were Hindu and my Islamic faith teaches me that only Allah knows what will happen to our generations tomorrow. Neither you nor I can say with conviction that the progeny which we leave behind, under the green flag, will be Muslims. We simply don't know. Also to exactly which version of Islam are you alluding to? We are multiple sects today and the way things are going we will be many more tomorrow, with each sect swearing by the Book that they are the right ones and that the other's are wrong. Our takfiri ways will be our downfall.
The best course of action to adopt in the present circumstances is to hold fast to your faith and to allow others the enjoyment of their's. This nation's survival is not contingent or pivotal upon Islam. Although our birth was part and parcel of the unity which Islam gave us, today Islam stands to divide us more than ever. If we are to make our place among the comity of nations and define our future as a working and progressive state we must learn to function for the Pakistani people, independent of the religion of Islam. Our policies must be geared towards the betterment of the people while at the same time be shaded with the morals and values which Islam inculcated us with, not the other way around.
Take it from Turkey. Do we think we're any more Muslim than them? Heck they even had a caliphate! Today Turkey, albeit being a secular country, is an Islamic model for progress. It is the only Muslim country as a matter of fact that looks well on its way to crystallizing its position as a hub of power for the Muslim world.
I pray that you shed your myopic view of this diverse planet which we live on and learn to embrace other faiths and traditions with tolerance and appreciation. It is a colourful world and that is exactly wherein its beauty lies.
