May I presume that you are asking me specifically to answer that question?

I am no authority on the markets and short selling in particular. I probably am more vocal about shorting because their very existance I find annoying and consider such a fraud onto the public.

Short selling in what ever form does drive the price down because more shares appear to become avaiilable for sale than otherwise be.
On the flip side, when those shorters that are not insulated from the necessity to cover eventually are forced to cover, the share price is raised higher than it otherwise would be.

If it were just the exaggerated sp then I would be in favour because it adds volatility and promotes more extreme price swings. Thus especially for day traders it is an answer to a prayer.
However I am of the opinion that the fradulent action more than trumps the benefits to day traders.
