Black swan events being unanticipated, it is futile to worry about them. It's commonly retorted that terrorist attacks should be interpreted as unique because of their intent. Yet no one actually fears the intent, only the end result (death, destruction, injury). Intent is relevant to drafting a response, but not to the public fear. Intent without resources or sophistication is also not meaningful. It is further stated that they are special because they're attacks on the social order. Yet this is a truism, because they only have such an effect if people permit themselves to make it so. More mundanely perceived events like business cycles or crime rates (many small events rather than one large event like a terrorist attack) have the same capacity for social ruin, but are not as feared even as they are significantly more protracted. It's all inexcusable bias.
