Oh for god's sake, the mumsnet anti teacher cabal rides again, you lot are entitled to say the least.
Schools have uniform, for better or worse they are there and the rules need to be followed, its part of socialisation and the hidden curriculum. Lots of you would be the first to be complaining if someone else didn't follow the rules and gets away with it (see threads passim)
To liken rebelling against school uniform to Martin Luther King or anyone else is a fallacy, a false equivalence in fact, please don't compare kids at school with those who made massive changes to
Lots of parents quite like it, its relatively cost effective, for example if you take the most expensive uniform costs of ??300 quoted on here. That works out as ??1.57 a day, or ??7.84 a week but only for the weeks that your child is in school. That's not bad going really, less than what you get in child benefit.
You want your child to question everything and not do things that they deem unfair. Fine, home educate, you can't expect organisations to change just for you and your whims. If you have a real issue complain to the governors and they will do something about if they think its reasonable.
You think teachers need to "earn" the respect of pupils? Tell you what, I went to university, got a degree, and decided to give a fair whack of my time and effort back to educating others, that deserves respect. If I have to "earn" your child's respect because you told them that it makes life much more difficult to me. No one I work with picks on kids cause they don't like them, that's the excuse kids give for getting into trouble.
