Sometimes, we just forget, (both the one posting, and his/her readers), that written communication requires a little more work when contraversial subjects, (such as the one's dedpoet mentioned), are being discussed. Myself included. Without the benefits of tone of voice, and facial expression, a blunt opinionated comment, can often make someone appear arrogant, even mean. Junction Guy brought up a good point about people being different "on the phone". In most cases, the "written" version of these posters hardly indicates the kind of people they really are.
