I don't think so. Paraphasing of couse, but I've heard Keyes say many times that our unalienable rights come from God and that no government can deprive us of same. I think it would go against his deeply held religious beliefs to say otherwise.
From Alan Keyes on the Issues:
On the source of our rights
We have forgotten the principle that our rights come from God and must be exercised with respect for the existence and authority of God. . . .
You can't have it both ways. Either our rights come from God, as our Declaration of Independence says, or they come from human choice. If they come from human choice, then our whole way of life is meaningless, it has no foundation.
On the role of government
All human beings are created equal. They need no title or qualification beyond their own simple humanity in order to command respect for their intrinsic human dignity, their "unalienable rights."
The purpose of government is to secure these rights, and no government is just or legitimate if it systematically violates them.
