The one you're conversing with seems to be of the opinion that if something in life isn't handed to you then you have been "disenfranchised". It's an amazingly immature attitude but is also indicative of an attitude that seems to be expanding in American culture. As you have noticed, it can be rather frustrating trying to have a rational discussion with someone who has chosen to forsake logic in favor of victimization.
"Yes, but are you a Protestant atheist or a Catholic atheist?".- Northern Irish joke
"God is the name by which I designate all things which cross my path violently and recklessly, all things which alter my plans and intentions, and change the course of my life, for better or for worse."
-C G Jung
This is a problem in the black community and, if we turn a blind eye for the sake of political correctness, then we won't see clearly enough to be able to do something that would remedy the problem.
There is also NOTHING wrong or racist about pointing out certain areas that the black subculture needs to get fixed. Nothing wrong with that at all.
A video like this should be a call to action for black leaders in the black community to say, hey wait a minute, this knockout game, this glorification of violence, it's something we need to actively work to fix in our communities.
Everything in your life is a reflection of a choice you have made. If you want a different result, don't blame someone else, or expect others to make a change, you should stop complaining and make a different choice. Remember, the circumstances of your birth don't determine the outcome of your life.
