Actually this is the duty of state not to be blackmailed by religious extremists who use the excuse of religion for showing their political strengths. Pakistan is at war with itself, the whole country is under attack by suicide bombers and our own security forces, why the hell government allowed such processions in the heart of Karachi? Just ban these religious extremists, if they want to practise their religion, why the heck occupy main streets, go worship in your mosques or temples. This not religion, this is only terrorism and evil when you torch properties of innocent people who in no way harmed you.
