showing public opinion by celebrities.

There is ongoing debate over whether presenting private opinion realated to publical issues on Internet by actors or actresses would be acceptable or not.

Somepeople might argue that those behaviors of actor/actresses are not aappropriate because those cellebrities are public people who can affect public opinion of common people.
However, in contrast to the opinion, I strongly believe that celebrities have a right to show thier opinion involved in public issues.
The fundamental reasons behind this that at the first, they are one of the citizens who are protected by country's law and the second, there is not strong evidence which shows that their reference has huge affection to public opinion.

To begin with, actor/actresses are critical members on citizenes.
It means that they have a right to rasie their voice to support or oppose to a certain topic in this country like anybody else in this country. If someone try to ignore this right then he/she are denying the basic right of people in Nation to present their opinion with freedom.
Thus, actor/actresses shoud not be bothered to say publically.

In addition to the reason above, the second reason is that the there are not much influence on celebrities's opinion. Actually that argue is under judjing common public. Most people have their own opinion on public issue and not that easily affected by maintance of actor/actresses.
Rather, many people have a tendency to criticeze what they say. It is adequate process in democratic country.
therefore we should not ban celebrities from showing their own opinion publically.

In conclusion, there are no reason to prohibit actor/actresses from presenting opinion
they have their freedom to show their opinion and we have our freedom to show our opinion.
If that is not enough, you have your own freedom to criticize that.
