In an ideal world, Wikipedia editors would discuss only content and would post only well reasoned, informative comments. They would assume, unless faced with overwhelming evidence, that other editors were also editing and commenting in good faith. Personal attacks would never occur.
Unfortunately it's not an ideal world. Bad things do happen to good people. This chapter shows you helpful ways to respond to incivility and personal attacks directed against you or other editors. It also discusses what you should do if you slip up and use uncivil words, or worse, attack someone personally.
Note:
If you've just experienced severe incivility or a personal attack, take a look at "Initial responses".
