It may sound absurd to you guys but I'm quoting this from one anime(Naruto), "When two fighters/ninja/etc collide, they will learn their opponents will and thus know how to respond"(not the exact words). I'm still a beginner but getting hit by someone(specially bullies), I would assume that martial artists who have understood their art even slightly, would know why they were hit. And thus, knowing why they were hit would understand the assaulter. Turning the other cheek is a gesture that will depend on its effect. If you are turning the other cheek because of humility, it's good, no doubt about that, but what about your assaulter? Is is safe to say that martial artist should not just humble themselves by turning the other cheek, but to take action not just for themselves but for the benefit of the assaulter as well?
