Anne R. Allen gives out ten guidelines. (Admittedly she calls them “commandments” but, well. The atheist in me baulks at the phrasing.)
I’m sure we’re all guilty of breaking at least some of these at least some of the time; gods know I’ve done my fair share. I would also politely disagree with #9; ignoring bullies and harassers has not now and never will make them stop, it just makes the victims suffer alone. That being said, often the appropriate retaliation is difficult to gauge. So… it’s complex. I don’t have a good answer to that one.
