The Pakistani Government's continued lack of strong action against this tide is only going to strengthen the fundamentalists who are threatening to derail any semblance of progress made towards democracy in recent years. Democracy does not mean anything if the rule of the majority translates into the oppression of a minority.
Christians, Hindus, Sikhs and all other non-Muslims in Pakistan will remain unsafe as long as people like Taseer are killed because the government does not want to address religious fundamentalism amongst its ranks and those of the military. The section of Pakistan’s population calling itself "liberal" will have to conform to fundamentalist ideas, live in fear or leave the country. This would effectively end Pakistan’s pursuit of a democratic state.
