To be a writer is to invite criticism. It can be hard to decide with which critics, if any, one should engage. Polite critics can sometimes be acknowledged with courtesy, but as a general rule it’s best to accept their feedback in silence and not attempt to rebut their points, especially when one is discussing matters of subjective opinion.
Poison-pen critics should in nearly all cases be ignored, except when the author of such a letter offers one the possibility of a “teachable moment.” Even then, unless it’s a subject that seems in dire need of examination, most such impulses to retort to one’s detractors run the risk of leading one to self-immolation. In those rare instances when one elects to respond to a detractor, a measure of restraint still is called for.
Every once in a rare while, however, one must sound the trumpets and let slip the dogs of war.
