Once you've decided which battle to fight, spend some time considering your approach. Remember the golden rule. Since more stories have been reporting the downfall of Apple, more Macintosh users have become outraged. Reporters are no different. 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. When you do finally sit down to write your e-mail, letter, or FAX, make sure you are relaxed. Being tense and upset will only hurt your writing.
