The constitution doesn't say anything about a lot of things, it was written 200 years ago. Nothing about drivers lisences, nothing about civil aviation rules, nothing about social security, we could go down that road forever.
You're right, the Constitution doesn't say anything about these things becaue they are not rights.
The Constitution, regardless of its age, is the Supreme law of this country and should not be disregarded. It can be amended if times change, but it should not be ignored or changed unofficially by either of the branches of the government.
Now Civetcat, you may say, bs - health care is important and just because the Constitution doesn't address it, it should and therefore, we'll consider it a right.
Well, keep in mind that if we all don't protect the Constitution that we will suffer from its abuse and neglect. Case in point, look at how Bush has messed with our civil liberties.
If you don't adhere to the Constitution then you cannot complain when others deviate from it.
