As has been pointed out, the behaviour on Newsgroups is far worse, and I suppose Mudcatters should be happy that considering the number of people now here, the constantly angry ones are still a tiny minority.
There really are two separate entities operating here, a large group of decent polite people who ask and answer questions, discuss even volatile issues with intelligence and courtesy, and in general, have satisfaction in their lives.
You can't imagine how that annoys a small angry minority who thrive on conflict. Thrive is not the proper term, they NEED conflict to survive each day. One of the angriest people on this forum gleefully welcomed back a presence who has become legendary for his sheer meanness. No uglier self-portrait could be painted.That person's anger, self-loathing, and future intent here, was made perfectly clear by those few words. One ally leaves, another reappears.
We must know that these angry people will NOT go away. Anonymous posts on a very tolerant site may be the last place that their behaviour is tolerated.
