I tried "walking away" back 9th grade. It didn't work out so well. They would follow me and keep punching me.
Word got out, apparently, that I would "just walk away" while they were free to pummel me. The result was I started getting beat up on a pretty regular basis (nothing builds those young self esteems like coming out victorious in a "fight"! And I was sure thing! Didn't even fight back!)
It ended up being the worst school year of my life.
I can laugh off barking, walk away from tough talk, but I stopped walking away from aggressive physical contact in 10th grade and haven't regretted it one bit.
Once somebody touches me or tries to touch me in a violent manner, I will do my best to make them regret it.
You can judge all you want, Dark Gift Concepts, but I find I am much happier this way, win or lose.
