Is shorting unethical?

price can be realistic only when both sellers and buyers are forceful. look at what is happening to sugar price. Shorters of sugar futures could have brought the prices down...Shorters are necessary. They look like villain but they are not. Rather they are savers. Look at steel/commodity stock prices...somebody needs to short it....Japanese are bit relieved as people started shorting yen against dollar......shorting is critical to maintain balance.....u don't know what one sided bulls can do to our lives....harshad's and ketan's.........
