Regardless of your personal opinion about the accuracy of this description, don't share your outlook. Chances are, an author has already received multiple derogatory and offensive e-mails. Your goal is to get your message across. That can't happen unless it gets read. Even well-thought out, logical, precise, and clear arguments won't be read if they are preceded by insults.
