There's always this feeling that shorts are predatory and making money off other people's demise. Kinda like betting the "Don't Pass" line in craps. Stocks go up, everyone wins right? Oh no not those pesky shorts trying to drive the price down. But the misinformation and hype from the long side is actually worse in general, and shorts aren't to blame for misplaced greed and hype.
If I am long on a stock I applaud the shorts. After all, if they are wrong, they have to buy back and drive up my price more. Also when a company is over-hyped or worse and outright fraud, short sellers can bring attention to this and slow the impending bust that is going to happen. I personally had shorted a lot of stocks in the past and they are almost all bankrupt now taking with them the sheer speculators that over extended themselves.
