There are so many problems with this. Do you fear everything then? Because people can die from absolutely anything, and what you said makes it seem like you're the sort to suffer extreme paranoia over everything because of the threat of death. Do you laugh at car crashes? Laugh at the common cold or find it harmless??
People are laughing at the Swine Flu virus because it is proving to be a joke, until anything serious happens, it shall remain that way.
