I experienced directly some uncivility recently on an oil disaster thread. While not pleasant, I expect it when you have a large group of mostly strangers, of varying degrees of maturity, together in an online forum. There will probably always be a few rude juvenile assholes who unleash. It would be nice to see a consistent ban rule in such cases, but I don't expect it either. As with many things in life, the world would be better if each individual would follow something like the Golden Rule.
