There are tons of behaviors which are great if you're right and bad if you're wrong. Should we never stand up for what we believe in? Should we let others decide things because we might be wrong?

And keep in mind that bad people won't care about these arguments. Only good people with reasonable and healthy self-doubt will be convinced to make less of an impact, and that's the opposite of what we should want.

I'm not at odds with your opinion, I agree. My point is that a lot of other fragile attitudes impact the person holding them. But a cavalier attitude like with Jobs or people set on having an impact on the world is fragile in that it can impact many others. That's the only concern with me.
