Some People Send Angry Emails!

What a cranky email! Why do people get so cranky? Gosh that is a cranky email from a person to another person, in this case, from a magazine publisher (or former magazine publisher, I can’t keep track) to a blogger. Why aren’t they on the same side of whatever they are arguing about? What are they arguing about-status? Respect? I’m not sure! What could possibly drive someone to send an email like that?
