If your intent is actually to leave FR, then just walk away. It is not all that difficult to shoot your screen name in the head, if that is actually what this is all about.
You've summed the situation up well.
Regarding the complaints in these "I'm leaving" threads, I think they're grossly exaggerated. Have there been some over-the-top comments by social conservatives in the Schiavo threads? Of course, but there also have been some over-the-top comments by the pro-Michael Schiavo people as well. Yet those people leaving because of the lack of civliity on this site only seem to be concerned with the comments made by the side they disagree with. When they suggest that social conservatives are just as bad as leftists, or they ping their friends to insult any poster who disagrees with them, or they say that because those social conservatives have *not* been purged from this site, that FR resembles a Communist regime, they've got a heck of a lot of nerve to complain about the name-calling on this site.
