It can, but that's situational. If it's some goomba on the street, there's little downside to him talking **** with his buddies that night. Most of us don't live in an area where we have to worry about gangs and such. With bullies, fighting is rarely necessary to back them down - that willingness to fight that DB and others have mentioned usually does the trick.Depending on the age and where you are, being considered a wuss could be a huge downside. It may have the potential to guarantee that the harassment will not only continue but it will also get worse, such is the case with bullying these days. Sometimes it's better to may Bullying an expensive practice. Every time someone bullies me, they earn a punch in the face. From there the bully can determine how many "frequent flier miles" on bully airlines he wants to earn. I'm pretty sure that somewhere down the line the bully isn't going to see that other kid as a destination.
I don't know how adult bullying is these days, but my approach has always been. "Come get some, if you want to" and " he must have not cared about it to much because he kept walking." The first one has the logic of, if someone is willing to go all out to the end, then maybe it's not worth messing with that guy. The other one has the logic of, if someone doesn't care enough about harassing to the point where they want to hit me, then I'll let it go and will be more than happy to walk away.
The one thing I don't ever want to appear is weak. The appearance of weakness attracts predators
