I'm only 31 but I was raised the old fashioned way. Some of the very first lessons my dad taught me was "Don't let your mouth write checks your ass can't cash", "Don't start something you can't finish", "you roll the dice, you pay the price", and "respect your elders." Looks to me like the guy that got knocked out needed to learn these lessons the hard way. To many punks think they can do whatever they want and say whatever they want to whoever they want without being accountable for their actions. I don't get where this sense of entitlement comes from. I don't condone violence, my reaction to seeing this man get knocked out was disgust. But if you keep getting in someone's face and talking shit to them, it better be for a damn good reason and you better be prepared for this because this is and always has been the world we live in.
