The Frustration Aspect: 
In my experiences it seems that a majority of people, from all walks of life, for the most part, either don't care, are too ignorant or are just too consumed by nonsense to realize what's going on. Whether it's the media, politics, religion, or the extremist ideology of being politically correct. All of the aforementioned issues tend to raise a lot of questions derived from being a skeptical person. Some may call it argumentative. I call it digging through the bullshit and refusing to accept the most popular or politically correct answer. People have grown to be way too sensitive.
I feel that if you're not frustrated, then you have no clue as to what's going on around you. From war, to feeding foreign countries before taking care of our own first. From working day in and day out, sometimes two jobs only to struggle and barely scrape by while falling deeper into debt, to bird-brain celebrities getting more news coverage than the men and women fighting and dying overseas.
I can easily rant on and on about September 11th 2001, broken borders, racial double standards, airport security, healthcare, cell phones, hip-hop, street slang ebonics, "reality TV", shallow fashion trends that are taken way too seriously and the robotic population that simply accept things for what they are and never question authority, but then I'll be here for days. 



The Sarcasm Aspect:
I'm into Hardcore music and have been since the late 1980's. For those who do not know what Hardcore is, it's a derivative of Punk Rock. I've been asked on many occasions what kind of music I listen to by people who have no clue.
After trying to educate them to no avail, I tell them, sarcastically, that I listen to "Angry White Boy music" and allow them to figure it out for themselves. Interpret it how you will.

In the end, I'm just a guy with a big mouth, strong opinions and just a little pissed off. (words from the AngryWhteBoy)
