It's unfortunate that you feel the need to label someone that you don't know as selfish, although I do think anyone that knows me at all would find that laughable. So let me just tell you a small amount about myself, and what I do to try to improve the world around me in a positive way:
In addition to the things mentioned above, I try to carry myself with kindness as often as possible and I treat everyone I come across with equal respect. I like to believe I don't have a discriminatory bone in my body.
Now, I'm sorry you're offended by my attitude of trying to make my immediate community a better place in lieu of getting caught up with every world issue that I cannot solve. Maybe you'll respond to this reply more positively without labeling me something that I'm not because this is a more honest and straightforward explanation of my original comment, or maybe you'll accuse me of lying - I guess I shouldn't care at this point. However, my overall message remains: I think people get too caught up on the negative things they can't control when my belief has always been that if you improve yourself and the world directly around you, then you'll notice that the world in general doesn't seem so dark. Not to mention, I've found that by occupying my time helping out those around me is rewarding, and doesn't leave me too much time to get caught up in the news story de jour.
I'm sorry if my tone offended you, I was simply trying to shed some positive light in agreement with the comic strip.
