That's great. I am countering the notion that evidence is not required because it is 'common sense'.

[stormfather]

Actually you just said that common sense would indicate a natural origin, which was, at least in the case of SARS, just refuted.

[Eisenstein]

No, I am saying that relying on 'common sense' is stupid because it can take you in any direction you want since you aren't going past a surface level evaluation. You just proved it by having to dig a little to try and refute my 'common sense' take.
