One of the unsavory aspects of internet forums is a tendency to say things to others that we would never say face to face with someone and expect the outcome to stay civil. If some of these verbal attacks had taken place face to face the result would be a black eye or worse. I know that
some of these hyperopinionated (t)wits wouldn't say some of the inflammmatory things they say if they had to get in someones face to do it.
Oh, the courage we can muster from our anonymity. I try to conduct myself on the internet just as I would if we were in the same room together.
