This song is about life and the challenges we face in it. It's about getting rid of the gray that we have and only recognizing the extreme ends of the spectrum. Also, after recognizing the extremes that we encounter in life, we must also recognize our willingness (or unwillingness) to show them and fix it. "I am covered in skin" is my favorite line. It means that we defend and protect ourselves from the evils of the world in different ways and at all costs. But in the end, we must pull down our defenses, and ignore what the world thinks, and act with out judging ourselves or anyone else.
