the merits and demerits of censorship and if it is neccessary

In my opinon, censorship should be used and is neccessary as it has many positive points.

One reason why censorship is neccessary as it protects our youth against negative social habits such as drinking, a pormiscuous sexual lifestyle, smoking, drugs and gangsterism, among other undesireable values. Censorship is vital in protecting our youth who are still not mature enough to watch these without becoming negatively influenced and learning the wrong social values.

Censorship of advertisements can also help steer the economy from luxery goods to capital goods and thus make it more productive, especially to a young one. For example, by censoring beauty advertisements and promoting other ones such as for homes, people will be encouraged to own homes instead of going for plastic sugery. This home they have allows them to have capital that for example can be used to get loans from banks. Censoring advertisements in the medical and law field also ensures that costs are kept down so that consumers are paying not for the image put on television but rather for the service instead.

However, there are exceptions to this. Censorship should never be used for political control or propoganda. One example would be in N. Korea now, the only dictatorship left in the world, where people are not allowed to get any news of the outside world. Other examples would be Germany or China in the past during the time of Hitler and Mao Zedong respectively.

Thus, censorship is neccessary except only in certain exceptions, mainly to protect our youth and to steer the economy.
