Most of us are guilty of it. However, we watch football and know, at least, the fundamental rules and principles of plays. We know that hole-in-one, home run, or 3 point play are not football terms. But none of us feel qualified to successfully coach either team in the Super Bowl
Dawkins, a prominent much admired scientist and educator is a leader in his fields of expertise. However, this does not qualify him to coach Believers. He knows some terms, knows some well-known players, and talks the talk.
However, he cannot be objective, or walk the walk because as a Non-Believer, his opinions are subjective, That is because, IMO, the beliefs of a Non-Believer are just as subjective as those of a Believer. Thus his faith in his beliefs are as strong as that of the Faith of Believers.
Yet he felt qualified to critique the reactions of Believers to "one of their own". His celebrity is what prompted his proselytizing being published.
