Is there any evidence at all that teachers are currently distracted? You know, any?
No, however there is evidence that clothing, even non-offensive clothing can be considered distracting. The article presented an example. A way to prevent issues like that from taking up time and to eliminate the possibility of distractions.
Your not talking about realistic scenarios, you are thinking about unrealistic scenarios with logic bent to fit your case.
I am sorry that we don't all look at the world through your rose-colored glasses, it's not unrealistic to believe that clothing can be distracting. To say otherwise seems like you're not being realistic.
...Yes it does.

If the Constitution says you have something, then it is a legal right because the Constitution directly impacts law.
What I am saying, among other things, is "freedom to wear whatever you want in school" is, in my opinion, not a constitutional right.
There is only once source that has been presented, while I find no flaws with it - I don't think it is more valid than any of the multiple ones I have supplied.
So let's say they're both equally valid? Does whoever of us presents more supporting evidence win? I'm not looking for other people to explain why it's a good idea to you, I'm looking to do it myself. You know a debate, I bring up points and you bring up points.
If we wanted studies we could google them ourselves.
The fact is the burden on proof does not rely with me advocating for the protection of rights but those that wish to remove them. A single study in the midsts of several others that state uniforms do not serve any greater good is not all that convincing.
Oh...
I have provided at least one.
There is only once source that has been presented, while I find no flaws with it - I don't think it is more valid than than the ones that were supplied to you.
So you are saying that disregarding the constitution and removing rights protected by it isn't wrong? Really?
Because this is a CONSTITUTIONAL issue! We should not disregard rights as easily as you are advocating.
What I am saying is that we are talking about a matter and whether or not it is "good" or "bad" cannot be determined by the constitution because the constitution can be wrong, misinterpreted, and misrepresented.
I'm talking about the benefits of school uniforms versus the costs of school uniforms. You can say that currently it's not constitutional but that doesn't remove any of the merit of school uniforms.
You can make a fantastic argument that requires the restriction and government control of the press - after all, if the government controls the press than anything dangerous to this countries security never gets out and people across this country are safer. Does that mean it's American? Does that mean we should allow it? Absolutely NOT. It would be so much easier to silence racists, bigots and horrible people - should we disregard our freedom of speech, if only slightly, to remove society of such filth? Absolutely not!
Why not? You make great points but you don't have any reason to support the liberties. "Freedoms are good because they are!" or the "Braveheart" argument is invalid. Freedoms can be bad and regularly we limit and modify persons freedoms for the benefit of the country and that's okay. So why assume that just because the removal of freedom would have to happen that it's automatically a bad thing?
We shouldn't allow the government to control the press because it would give to much power to the branch that controls it. Media is too powerful a tool for any one entity to have so there must be competition amongst media outlets.
The argument is that kids, they don't know best, so we have to tell them what to do more often than not. The "kids won't like it" argument does not mean that it's a bad idea! Is ad populum childrenium a logical fallacy?
What you don't seem to be able to fathom is the fact this is a CONSTITUTIONAL ISSUE, this is an issue of RIGHTS - the RIGHTS of a student. Therefore what the Constitution says IS the focal point.
We know what the constitution says, but is the constitution right? Should it be changed? Would it be advisable to limit the constitution in this manner?
