I saw this on Metafilter. I am not a member but I enjoy almost daily reading on the site. I would offer than you have an unaddressed aspect in regard to those than are called trolls. Specifically Forum members who try to end a debate by labeling someone a troll. I am a member of Syracuse.com and DailyKos. I started posting maybe 7 years ago on Syracuse,com after RWers brought God to the defense an UNJUST war. I am a Catholic who marched against the Vietnam War and for black rights and anti-poverty programs. Since I started posting I have tried to distinguish between what Jesus would support in the positions of the Republicans and the Democrats. To the Right Wingers on Syracuse.com I am a troll because I call them to account concerning unjust wars, the death penalty and their continuing efforts to strangle social programs in a bathtub. On Daily Kos I am called a troll for not supporting "gay rights" or abortion. My views are consistent with my religion. Moreover when I was younger I developed a great appreciation for the Amish and Mennonites who view things in a similar manner but maybe to a greater extent and with greater consistency than the Catholics, I am civil and stay well within the site posting rules. I have had my posts and user name constantly deleted on Syracuse.com and that is fairly easily done there by any poster hitting the "Inappropriate Post" button. The modest size gay friendly community within DailyKos are very hostile to any posts that are in opposition to their goals.
