The online people I have known over the years have truly suckish conflict resolution skills. They do all the unhealthy shit in this link. http://www.helpguide.org/mental/eq8_conflict_resolution.htm . Offline, it's a mixed bag. The older folks who have been around and understand their triggers do a pretty decent job. However conflict resolution is not something I see as being taught or encouraged.
Read the link, it has great information. It is something I learned in interpersonal communication in college. Knowing and understanding the above stuff in the link, will help you in relationships.
