Let's make sure we all understand the separation of powers concept. Unless I have it wrong here (please correct me if so!):
1. The Judicial branch (Federal and Supreme Courts) do not make laws, they interpret them, as needed.
2. The Legislative branch (Congress and Senate) makes and enacts the laws.
3. The Executive branch (President, Justice Dept, etc.) enforces the laws, as needed.
So, yes, the legislative branch wrote the Constitution. When they choose to enact more laws, they have to make sure that it is done in context of, and not in opposition to the Constitution.
If not, then the law is flawed. And, I also acknowledge, so may be the Constitution.
Which is why I believe that when a law and the Constitution are in conflict, the Legislative branch has an obligation to either (a) change the law or (b) change the Constitution. Whichever makes more sense, and whichever they can get sufficient votes and ratification for (since amending the Constitution is a hell of a lot tougher process).
However, if we can avoid passing laws (and the inflammatory BS from politicians) that are in conflict in the first place, then the need for a fix does not arise. It is in this context that I believe reminding the Legislative branch of what the Constitution states, is relevant.
So, given that Senators and Congressfolk are often not legal or Constitutional scholars, then reminding them is a Good Thing. My wife, a Tax professional and Securities and Insurance expert, was required to take classes
every year to maintain her licenses. You, as an eventual lawyer, will need to do the same to maintain your professional status. Why shouldn't the leaders of this country be required similar on-going training?
Clearly, we have to agree to disagree on this topic. You think it was a symbolic gesture. I think it was correct training (and re-training) material.

Done?
