Can't always tell who the trolls are. We have a vocal minority around here who would bash the President just because it's Wednesday.
Saw Dolphy in action a couple of places. He is a troll. Just tune him out. Feeding the DUers just encourages them. Makes them think their rabid stupidity is credible commentary
You've been around long enough to know FR has calmed down considerably. When W was planning to run for president, I supported him...and got sooo flamed by lots of FReepers (who've mostly been banned now)... I learned to tread very softly in those days.
