For the most part, I believe they do. With possible exceptions of post offices and such. As well as most of the Amendments that follow the BOR, which seem primarily to weaken the BOR.
Which Amendments [except for income tax] weaken the BOR's?
Yeah, some of our past foreign policy has sucked, and if we followed Geo Washington's advice from his farewell address, we probably wouldn't have funded and armed our enemy's enemies.
But no matter how you slice it, one of the only problems with the War On Terror is that we don't have a Constitutional, Congressional Declaration of War, or Letter of Marquee and Reprisal to kick ass on these scumbags. They are nothing more than pirates. You cannot allow pirates to terrorize us. You must declare war on the countries that directly support terrorists, and you must use special forces to execute warrants on terrorist leaders.
Personally, my only beef with the WOT is that it's not Constitutionally "legal", and that we haven't bombed Syria and Saudia Arabia into the 3rd Century!
The 14th weakens states and moves the government further from the people, although this isn't expressly written into the 14th it has become case law.
The 16th (which you mentioned) is obvious theft of an individuals right to keep the fruits of his/her labor.
The 17th on its face seems to give more power to the individual but actually makes it so that Senators have little need for small government or state governments.
The 18th, fortunately, was repealed.
The 21st seems okay since it repeals the 17th, but what about section 2?
The 22nd removes the power from the people to elect a President to a 3rd term... apparently the people are too stupid to have figured out in 8 years whether or not the President is any good.
I'll admit that some of the others actually strengthen individual rights.
