noble I'm pretty sure that is not the take away from uniform threads on here at all. It might be your take away.
Mine is that most people in favour of uniforms have never actually experienced a non uniform system and are, as Giles says, basing their opinion on Mufti days, which is a bit like only allowing a child chocolate once a year and then concluding from the fact they stuff themselves til they vomit that if they were allowed chocolate every day they would do the same thing every day.
I swallowed the "equaliser", "easier in the mornings", "sense of identity" and maybe even "school pride" arguments whole when I was a teacher in the UK - I even remember using uniform as a Year 7 class debate topic and year after year engineering the debate to ensure they came to the conclusion they actually should wear uniform like a good little representative of the school 
However having moved to a country where school uniforms are very rare (there are no schools with uniforms anywhere even vaguely local) I have changed my mind totally. The arguments against uniform are utter hypothetical nonsense dreamt up by people who have never actually paid any attention to how schools in Europe run without uniform.
All my kids wear trainers to school unless they wear flip flops They wear jeans, in summer they wear shorts. They wear any colour they want. DD has purple streaks in her hair. DS1 wears a neon orange head band. In winter they wear neon jackets (with reflectors right up to secondary age) that are more easily seen when they walk to the bus stop. None of the predicted terrible consequences of not wearing uniform have ever happened, at all...
The only thing we've clashed heads over is DC1's wish not to use a proper structured school rucksack when carrying her heavy books to school any more... that argument could have happened in the UK too!
