Murder is murder. Blasphemy is blasphemy. It's just a matter of how you connect these two sentences.
Murder is murder and blasphemy is blasphemy. And the country has put "but" in place of "and" and is changing the order of the two sentences. Although the political parties have a different debate altogether- pointing fingers.
I believe the blasphemy law is right in its place and
About Freedom of Expression and Blasphemy:
I find many people complaining that the "ghairat brigade" troubles their freedom of expression. Let's define both of these terms. Does the term "ghairat brigade" refer to those who support the terrorists? Does it refer to those who demand the unconditional release of Dr Afia? Or does it consist of those who support the blasphemy law? Because I feel all these groups might overlap but are in no way the same. For instance, Dr Sarfraz Ahmed Naeemi was a strong antagonist to terrorist forces and was martyred in his fearless struggle by a suicide attack in his Mosque. He issued fatwas against terrorists but I am sure he would have supported the blasphemy law, had he been alive. So generalizing people who disagree with you as the "ghairat brigade" is much more narrow-minded than the "ghairat brigade" itself.
As for freedom of expression, we need a definition too. In other words, we need to know where freedom of expression becomes a hate crime. Is a guy whistling at girls freedom of expression? Is a VJ prominently displaying her low neck on TV freedom of expression? Is a white person not allowing entry to a colored person to his shop freedom of expression? I believe the line is drawn wherever the feelings of a particular community are hurt.
All life is sacred. There is no denial to that. And any harm to life without any judicial grounds is a sin and deserves equal punishment. Same is the case with the murder of the governor- no one person has the right to declare someone a criminal under any law. This is the way educated and democratic nations deal with their issues. We have laws governing every aspect of our life and courts with judges to make decisions. Even in the Shariah, only the Khalifah or Qazi has the right to give a decision. And Khalifas don't operate underground. The murder is unlawful, with no religious or moral grounds. The governor did not even commit blasphemy the way I see it. He expressed his opinion, but was not careful in choosing his words. Calling the law protecting the honor of Prophethood a black law was like an open challenge to the already infuriated Pakistani community which had lost all it's faith in the government.
Comparing the murderer to Ghazi Ilm-din Shaheed is confusing too, as to whether people want to demean Ghazi or exalt the murderer.
The Next Step:
Pakistan is an Islamic republic. Most, if not all, Muslims love the Prophet (PBUH) and hold his respect above their lives. Most of them are uneducated. They know Islam but do not understand it.
