No, it's just the opposite. I single exception does not counter a general rule.
The Professor's World: "It's not insane to play Russian Roulette with a loaded gun because I did it once and am still alive".
One of my professors once cautioned me against the use of analogies for precisely the reason why you should stop using them. That is, although they seem to at least make sense to the user, analogies are frequently ridiculous when you actually read them.
For instance, the analogy you have attempted to make here to RWP's point breaks down immediately, because the conclusion you have drawn from your premise doesn't follow.
In case you didn't understand what I just said, I'll just point out that still being alive after playing Russian roulette doesn't equal "not insane." After all, one can be alive and insane, yes?
So If you claim that all crows are black, and I show you a white crow, you can still go on and claim all crows are black. That's amazing. It's not logic, it's not reason, in fact it's total insanity, but it's amazing.

Scientist. "Yes it does. Science says the earth is 4.5 billion years old. But a literal reading of the Bible implies it's 6000 years old.
