I was in the Army and I hated most aspects of it. But one thing I really liked was the uniform. Just waking up and putting on the BDUs and not having to think about what to wear was great. Also, it eliminates comparison between others. You don’t have to worry if you’re under-dressed or over-dressed cause you are wearing the same thing as everyone else.
It worked in Star Trek, right? Well, unless you were a redshirt.
I hate uniforms because I hate the concept of uniformity, especially in a social setting where uniformity is achieved through coercion or force. If you let them take your individuality, they’ve already won over half the battle.
