And it was just the same thing for segregation. "Don't try to tell us that we can't force our n*****rs to the back of the bus."
Amendment 9 and 10 of the Bill of Rights said so!
No. 9 - "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people."
No.10 - "The powers not delegated to the United States (i.e. Federal government) by the Constitution, nor prohibited by it to the States, are reserved to the States respectively or to the people."
The Founders' intent is controlling in any interpretation of the Constitution. The Bill of Rights was understood, from the time of its framing until 1865 to be a prohibition against the powers of the Federal Government. You are interpreting 1860's issues with a 1990's view, but fail to try to understand issues as they were viewed in 1860. The following quotes will help in that shortfall!
"Were we directed from Washington when to sow, and when to reap, we should soon want bread." --Thomas Jefferson
"...[T]he States will retain, under the proposed Constitution, a very extensive portion of active sovereignty..." --James Madison, Federalist No. 45
I put these quotes here because you are too ignorant, or uninterested to research them for yourself.
