Is there a reason to not worry when you read things like this
Registering yourself as a blogger describes the idea of having your freedom curbed, your every move monitored... It's an assault on your existence as a person who has been bestowed with the ability to think (rationally or otherwise)
If a different country wants to do it, then let it be. Why emulate it? If you look at their history, communism was part of their not so distant past. We instead have fought tooth and nail against it, lived in general fear during the emergency years, not allowed a movie about an old communist 'hero' to be screened here, yet when it comes to freedom, we are sometimes treated like 5 year olds. And you can't force people to be responsible.
I believe that people, regardless of who they are will be able to make conclusions for themselves based on what they read. Introducing this move is akin to telling off the lady at the end of the street to register herself as an official gossiper!
