Anonymous Postings

Why do people choose to post comments on blogs without stating who they are? My last entry, Bumper Stickers and Window Clings struck the nerve of one individual. The person chose to "hide behind the curtain" and called me resentful without giving any specific reason why they felt that way. My blog contains my opinions and how I see and feel about everyday events. Resentful? No, not resentful, merely writing how I see things. You don't have to agree with me, but use common courtesy and either state your name or e-mail me with your thoughts. I will not reply to anonymous postings. By the way, I am able to track any/all postings, so I have a pretty good idea who the anonymous posters are. In the future, all anonymous comments will be deleted by the administrator.
