Alternative to bad parental advice: "Stand up to bullies"? - eviltoast

When growing up my parents taught me to stand up to bullies. (We’re talking about verbal abuse and manipulation, not physical bullying.) Following that advice as a kid led to mixed results yet it’s stuck with me into my adult years.

These days though, using this advice only seems to backfire. When I give them what they’ve given me, the bullies just get more angry and use that to justify their continued bullying. They see themselves as the victim.

Any suggestions that would be more helpful?
