actually, i've been on this site and others for years, and debated things quite amicably with others.  and i've never called anyone names or insulted them.  and i've never gotten upset at others if they didn't either insult me or my work.  this is the only site out of several i frequent where i've seen this kind of behavior, and seen it go unchecked.  this is, in fact, the first time in about 8 years i've felt the need to pull out of a group or a community.
