Blocking site means that Govt. wants to conceal some facts or views. In fact, if Govt. does not let the people think in both ways, for & against, it means, Govt.does not want to be questioned which is against the basic law of democracy. The better way will be to let the freedom of website remain and Govt. should streamline its system to reply back (on its website or connected website) on all provoking statements as made on objectionable sites.
