Really? You don't confront a colleague about not doing what he promised, but you go to your boss, because it could turn violent? You don't confront your neighbour about the noisy party, but you call the landlord, because it could turn violent? You don't confront your teammate about not giving enough passes, but you complain to your coach, because it could turn violent?

You are showing quite a lack of imagination in applying the maxim you complain about in your top-level post.
