@average_random_joe It is in that case, but that's not the impression I got from what you said before. I though that it was all one confrontation. Lets go back then. Words were exchanged and you knew each other. That he was trying to humiliate you knew right away, not from third time of getting kneed. You knew it from from context as well. You also articulated what you wanted, is that him to leave you alone, clearly. At that point communication was over, no new communication took place, it was just a power struggle between you two, and you came up on top. Simple as that. He could've came up on top instead, and then things would have been his way. There is no communication in punching or kneeing.
From what you were saying before it sounded like, someone just silently came at you tried you knee you 3 times in the groin, and was so bad at it, that instead of being hospitalized you punched him so hard his nose probably broke, all still without a word uttered. All that misunderstanding just cause you were trying to push your BS about violence being communication.
