Clothing Contoversy

There's been a lot of controversy at DS's school this year. The latest issue was about the dress policy. There's always been a lot of different ways kids dress from preppy to wearing multi-colored hip hop clothes. There was one well known student that was reprimanded for wearing gang colors. Once the word got out to the rest of the school a text went out for everyone to wear red shirts (apparently that's what he wore). DS came home and told me about it and I tried to explain to him that it wasn't JUST the color of his shirt but how he wore it with the rest of his clothing. As I assumed the next day an email went out about the incident and of course there was more to the story (he was not changing his clothes and not only wore his clothes a certain way but had colored laces and such as well). The funny part is that DS isn't allowed to text so he had no idea and wore a red shirt (his favorite color and with print) anyway. It seems to me that his generation wants to have a say but doesn't have any insight nor do they understand the politics. Are their parents not teaching them anything?
