Juxtaposition

I have some very contradictory values, which I somehow place equal importance on in my own personal morality. For instance, I think that individual rights are extremely important, but at the same time I think that killing one person in order to save many others is perfectly acceptable. Freedom of expression, to me, is the essence of humanity. At the same time, I often say that people who say stupid or irrational things should be hit with sticks. I think that abortion is a highly personal, individual choice that the government has no business regulating, but I also think that there should be restrictions on who is allowed to have children. I value rational and critical thinking above all else, yet I regularly make decisions based on intuition and impulse. I think that prejudice is irrational and inexcusable, but I believe that your appearance is important and frequently make fun of how people are dressed. I also do not dress that well myself. I am cognizant of the manipulation techniques of advertising, yet I buy a lot of name brand items even though the generic version is cheaper. I think that the amount of attention paid to idiotic celebrities is disgusting, but I frequent gossip websites and stay updated on the state of Heidi and Spencer's relationship and Britney Spears's mental health. I think that Dr. Phil gives psychology a bad name, yet I find myself watching his show.
How is it possible to have completely opposite beliefs at the same time? How do I contain these contradictions in my mind without them cancelling each other out? I can't even rationalize a way to hold these opposing beliefs at the same time. Maybe the sum of a person's personality is made up of their contradictions.
