Ever since the being of elementary school, I have always heard the phrase "life is unfair". It was the stock phrase for whenever I complained about something, and there was nothing that I could do to argue against it. I always some snarky kid in class who told me how bad everything was, and as I grew older, people only complained more, whether it be about school, athletics, or the rest of the world. This also included people who refused to talk about anything positive about America, regardless of their political opinions. What bothered me more, however, was that people saw this as a sign of maturity. This is heavily prevalent in media, as well. Stories with ideal heroes and horrible villains are viewed as childish and unrealistic, only to achieve acclaim when it has a lot of death and other stuff, which I am fine with. However, stories with jerk anti-heroes and "sympathetic" villains (ie villains who are murderous sociopaths but do it because they hate pollution or some petty crap) don't have to prove themselves as mature as they are already labeled as such. Virtually all of stand-up comedy and Simpsons-esk shows just make fun of people, events, and brands. With politics, the only thing that you can ever say without offending someone is by saying that both sides are stupid.
This all contributes to my main question that I hope you can answer: why does everybody try to be cynical? While I don't consider myself an optimist, I believe that there is more good than bad in the world. Is that immature?
