One of the more serious sins when participating in online forums is to start a flame war. When people begin discussing an issue in a place like an online forum, there is a tremendous amount of opinion generated on all sides of the issue. During the process of discussion and argumentation, some may feel offended and begin to make insulting or caustic responses that will inevitably trigger a similar reaction from the other party. And before one knows it, the entire thread of discussion has degenerated into a flame war, which is not useful to anyone. As a matter of good netiquette, it is always advisable to walk away or hold your peace when you feel that the online conversation may descend into a flame war.
