The basic idea is whether you believe in a secular Pakistan and a secular society (same rules/values/constitution for all relgion people Hindus, Muslims, Christians, Ahmadis, Shias, Sunnis). It is not just a name change but more then that. Essentially it is about whether you believe in Secular values or not. So what do you believe in?
Basically the state would treat everyone equally irrespective of religion. It does not matter to state whether you are Hindu, Muslim, Ahmadi or Shia or Sunni. The state rules have nothing to do with your religion.
Should I add your name in that list who believe in having a secular Pakistan and Secular society in Pakistan?
