And sometimes guys who go long shares are destructive too - mindlessly pumping overpriced stocks. In my opinion they're just as bad as doctrinaire short sellers.

There are good reasons for convertible bond investors to short shares of the company whose convertibles they are buying. It hedges their risk, and is not merely a speculative short position.
