Your best defense is to look like less of a victim than someone else in your vicinity. Kinda like pushing the sick and old gazelle to the outside of the herd. Lions gotta eat, we just wanna make sure those gazelle are sick or old. Of course, this strategy is probably a bitter pill for most of us.
Well...it's a functional strategy, but you're basing it on a false analogy. Lions gotta eat. The choice for a lion is, eat this
gazelle or eat that
gazelle, or starve. Teenagers don't gotta punch someone unconscious. Their choices in life, no matter how bleak, simply aren't limited to which person they punch.
