Dress codes have pros and cons of course. Most of it has to do with teachers and administrators wanting you to go to school to learn and therefore they don't want everyone worrying about what they or everyone else is wearing, there's the safety issues and concerns listed below as well. As an ex-teacher-in-training I can relate to those reasons.

However, some schools use it as a form of control. They use it to stifle creativity so that they can prepare the next generation of factory workers with as little distraction as possible.

I believe that a dress code is necesary, but not one that is so stringent that it becomes oppressive. Good luck finding someone that can walk that fine line though.

Actualy, not all schools have uniforms. The school I go to has some strict dress code, but that's to prevent "pants on da ground" scenarios and gang affiliation. Most dress code is made to prevent the students from looking like prostitutes and pimps (keeping a friendly environment). Dress code also helps prevent school shootings and such misshapes with rule like no baggy shirts, always wear your ID, ect. I really don't have much of a problem with it (but then again I only wear three different pairs of pants [washed constantly] and geeky t-shirts (mainly Star Wars.) and have only once ever owned a shirt that could technicly have gotten me in trouble [ because it was R2D2 and he had bleeped out language]. Rules are ment to keep society functioning, because those who went before us did something dumb along the way (or one of us did something dumb, same difference)

um this has absolutely nothing to do with mine craft
