If you're an indie author who feels attacked by readers on the Amazon threads, do not engage them. Do not call them names. Do not whine that you've been picked upon. And for heaven's sake, do not bring them up and call them names on another author's thread, thus dragging her into your battles. Just don't. Be polite and grateful to the readers who love you, and ignore the others with dignity. Please. The Amazon threads will be a calmer, happier place if you do, and you'll make indie authors as a whole look classier, besides.
