I can see the point of those saying that shrewd has a right to his point of view and I totally agree BUT:

Imagaine we are twenty people in a room and one or two of these people have a difference of opinion of a subject we are somewhat passionate about. This is fine and makes for GREAT conversation.

Now take the same room and imagine that most of the people had lost lots of money, backing something they truely believed in and one or two people were arrogantly laughing in their face about it. That scenario is no different to a chat forum. This is what gets me offside as rubbing someone's misfortune in is soooo unAustralian, even for a Kiwi...
