It is important to remember, whether one offers or receives a critique, that the poet asked for it and the critic was nice enough to read the poem, analyze it, and offer advice, such as it may be, free of charge. Critiquing the critic is poor form. A gentle clarification for a critic who perhaps missed something is acceptable, but anything beyond that smacks of ingratitude and rudeness. I am always careful to at least thank my critics for their time even if I have no intention of taking their advice. I also am careful to abandon a poet who does not accept my criticism with courtesy.
