> The amendments don't grant rights; they limit government.
They limit government by defining, in the fundamental law, rights that are prortected against government encroachment. Those aren't mutually exclusive alternatives, one is the means by which the other is achieved.
> That's why we call them inalienable rights. You cant "amend away" these things.
The quasi-religious belief that there are rights that exist "in nature" prior to law and which all governments are obliged to observe is a popular one -- and was with the founders -- and part of the basis for the use of the term "inalienable right". However, the exact parameters of such "inalienable" rights are far from uniformly agreed even among those who subscribe to the belief that they exist. You absolutely can alter which of the rights that some people believe to be inalienable are protected by a government through amendments; note, for instance, that quite a lot of people from the time of the founding through (and no doubt past) the time when this was, in law, settled at the point of a bayonet by the 13th Amendment, thought that the widely-accepted-as-inalienable right to property included the right to hold human beings -- and particularly for whites to hold blacks -- as personal property.
