You're confusing civil rights with inalienable rights.
The inalienable rights to life, liberty and private property are God-given, and cannot rightly be taken by anyone. That is the core principle that America is built on.
You can't kill a child. You can't make a slave of a child. And you can't steal the property of a child. Why is that so hard to understand? The founders called this fact "self-evident." Have conservatives fallen so far that they can't even see what the founders thought was so obvious that it didn't even require proof?
But a child's parents can take the property of the child, or deprive the child of liberty.
