Stupidity…

There is always someone smarter than you, always somebody who is not as smart as you—and do you always know who is who? This aphorism does not suggest that it is always wrong to note (and to lament) that someone is behaving foolishly. It merely states that one should not make it a habit, or be too free with such speech—not only because such speech is hurtful and slanderous, but also because it might be in error.
