So you are saying that I should not be afraid of a tiger, because they belong to the same family as the nice pussy cats I see everyday? After all, there is a reason they've been given the same name.
No :) I think that's actually what YOU are saying. You are comparing two virii that we could not observe for long in the wild (The Tigers) with some cat (Sars2). I think we have good evidence after 2 years that Sars2 is much more similar Sars1 and MERS - just from a KPI perspective.
