When a government does a filtering or censorship on the internet, we have to think about- what will be filtered?- why are these filtered?Then we can ask to ourselves. Is it appropriate?Many countries and some organizations actually do a filtering with various purpose and certain extend.For example, china is known to filter the internet for their political purpose, which is to hide any information that is opposing to the government. In this case, as a foreigner it’s hard to say though, political purpose means that the purpose is only for a certain group of people, not for all of citizen.As a grown up human, we have ability to know what is good and what is bad among the information out of the internet. A government not need to make a decision on behalf of grown up citizen.I saw many students talking about pornography. But, if a government found the website which is dealing with porn (it’s really easy to find these one by googling), the authority can raid on the website host and track the owner of the site. In this way, the porn site owner may be caught by policemen and be punished. This is the right way to block the inappropriate content creator on the internet.Blocking the all the website which is possibly having an politically opposing contents or sexually inappropriate content might block innocent homepage. Moreover, in many cases back in the history, government did a bad thing and used media to cover it up. Censorship on the internet may easily be used for that purpose by any government.For these reason, we have to be critical about filtering the web contents by any certain authority.
