Yes, black death is terrible. However, it doesn't mean that anything less than black death should be dismissed.
That's fine, you can use the Avian Flu's projection as an alternative to do the same analysis.
Does that mean we should shrug off and say the nuclear bombs are nothing to be afraid of?
You're actually weakening your own argument. Nuclear bombs are worth worrying about precisely due to their potential for destruction. So please add the projections for a nuclear holocaust to the same analysis I requested, and then we will discuss "the numbers" further.
