As Theodore Roosevelt correctly noted,

"It is not the critic who counts, nor the man who points out how the
strong man stumbled, or where the doer of deeds could have done them
better.

Teddy was wrong, and so is DO. For instance, I am not a politician,
have never run for any elective office, but I (and millions of others)
correctly judged California's now former governor Grey Davis to be
incompetent and we got rid of him. Good call and job well done. Many
other examples are available: the movie or art critic (do they have to
be active film makers or painters to judge?), the restaurant critic
(do they have to own and operate a restaraunt before passing judgement
on the service, ambience, and food?), etc.

The original poster correctly responded to the rhetorical question,
"when has Rutan failed?" But answering that question doesn't
necessarily imply disrespect. My guess is that Rutan, and probably
the original poster, would readily acknowledge that failure is a
necessary part of becoming great. This, DO does not seem to
understand; he confuses hero worship and perceived perfection with
greatness.
