Epistemological violence in America

The role of the t-shirt in society constantly amazes me. On the one hand, t-shirts are ubiquitous. Most everyone wears them. Thrift stores are lousy with the discarded and/or ephemeral. Music festivals often double as ironic shirt conventions. On the other hand, t-shirts have become a staple of free speech. Profanity, explicit imagery, and political statements are perhaps the most noticeable examples of t-shirt-as-sandwich board. I myself own several such shirts. A recently purchased shirt sports a picture of a computer and an office chair, the latter of which is made to look like a coffin. In other words, spending one's life staring at the screen is the same as dying. Go outside, see people, be alive!
I spend much too much time with my laptop. This t-shirt has caused me to reconsider my lifestyle, and to realize that I am not living up to the ideals my clothes espouse. It's one thing to not be able to afford your politics (i.e. vegans who cannot afford expensive synthetic shoes). It's another thing altogether not to practice what your preach. T-shirts with radical political and/or environmental messages fill one drawer of my dresser, yet I see my actions veering toward the mainstream, if not the lethargic. This introspection will perhaps shame me into action, and to move away from t-shirt poseurdom.
