You certainly have the right to hold your opinions, but in this discussion, we are focusing on the vision of the founding fathers of our nation, who had a distinct understanding of Islam that significantly differs from yours. For instance, Allama Iqbal categorically stated about the separation of state and church (i.e. secularism) that "Islam, no doubt, does permit such a view"
Unfortunately, in overly religious societies like ours, secularism is viewed as an attack on the dominant religion i.e. Islam, leading to misunderstandings and resistance to the idea of secularism.
Interestingly, the notion of the separation of State and Church, commonly referred to as secularism, was brought to Western Europe from Islamic philosophy. However, contemporary orthodox Muslims often reject the concept of secularism as a Western ideology incompatible with Islam. One of the most influential Islamic philosophers who played a significant role in shaping the evolution of secularism in Western Europe was Ibn Rushd, an Arab-Spanish polymath and philosopher. Dante's Divine Comedy, Chaucer's Canterbury Tales, and Rafael's fresco of the School of Athens all immortalize his contributions to Western thought. In the West, Ibn Rushd is celebrated as the founding father of secularism.
It is my belief that the fundamental problem stems from a lack of understanding of the all-encompassing nature of Islam.
