ReDquinox wrote: That is about as valid as saying the statement "ravens are black" is wrong because albinos exist. The fact that they are naturally black isn't changed by rare anomalies. Similarly, there are cases of mutated sheep being born with two heads (though almost always stillborn), but that doesn't mean that the claim "sheep have one head" can't be considered a reasonable assumption. (Seriously, don't even play semantics with me. Saying "ravens are black" is completely different from saying "have you seen a non black raven?". Because the answer for the question can be yes, if you have seen a white raven, or even a pink or purple one. You are just cluttering this thread with pointless posts I reply to out of bordom.)

(The fact remains your own rhetorical question fell plain flat due to its implicit assumption of absolute nature. It is definitely not useful in supporting your argument in any way. And if I were you, I would phrase it as "most ravens are black". This means you are aware the exception exists. Reasonable assumption is still an uninformed guess, after all.)
