We're discussing uniforms in this episode. If you look at the etymology of the word “uniform”, it basically means “one form”; it's an outward sign of the unity of a group, of the fact that they are all there for the same purpose, to work toward the same goal(s). This is as true for a soccer team as for a Scout group, and the intent is the same; some individuality is stripped away — and differences based on ethnicity and economic standing are diminished — in order to build up group cohesion. If individuals within the group are going to distinguish themselves, it won't be by their outward appearance, but by their achievements.
