What if we challenge the notion of the Holocaust, calling it a mere myth? The decision of Lahore High Court to order PTA to block access to Facebook is laudable. That is right response to the competition created by Facebook users who had set up a page called "Draw Mohammed Day" inviting people to send in caricatures of Prophet Muhammad. It is unfortunate that in the guise of the so-called 'freedom of expression' such outrage is committed and so often, against sensitivities of a large number of people in different countries. Facebook, quite amazingly, has expressed disappointment at being blocked in Pakistan. They think Facebook is a site "where people can openly discuss issues and express their views while respecting the rights and feelings of others. With now more than 400 million users from around the world, Facebook sometimes finds people discussing and posting about topics that others may find controversial, inaccurate, or offensive". That sounds alright. Except if you decide to use the right of free speech the same way. The West regards the Holocaust as a systematic state-sponsored persecution and murder of approximately six million Jews by the Nazi regime and its collaborators. If we challenge or ridicule the whole notion of Holocaust, call it a mere myth concocted by the West, will that be taken by the Facebook as something "people can openly discuss and express their views while respecting the rights and feelings of others" or will that be taken off the website by its administrators? -HAMMAD ZAHID, Karachi, May 22.
