Fair point, I wouldn't say simply being contrarian is the solution. Shorts do great work and can profit immensely from finding the truth, as they should, but personally feel the financial media is a Dr. Frankenstein which creates it's own monsters. There's plenty of examples of "common knowledge" in the year before the Great Recession. All sorts of talking heads lined up to re-iterate the _truth_.
It is possible to short a viable company into bankruptcy and win from it, this is something that should be acknowledged.
