By your logic, rights cannot be God-given, as man (and nature) regularly infringes upon such rights as life and liberty; how can the profane infringe upon the divine?
Rights are inherent with the individual -- however, he may enjoy only those rights he is willing to defend. You are alive only as long as you defend your life; you are free only as long as you defend your freedom. If rights come from a source external to the individual (God, the State), that source can opt to rescind those rights. However, an organism's very escence rebels against being deprived of these fundamentals -- we fight to our last breath to live, we rail against being caged. No, I believe it is self-evident that rights are inherent in the organism.
Rights are not inherent. They are endowed, and you are correct that they can be rescinded. Fortunately, it is not the state but God that does the endowing.
Rights, of course, are violated every day -- just as the 10 Commandments are broken every day. But this means is that those who oppress are in rebellion against God. They act so without authority and will one day have to account for it before an angry God.
Because rights are God-given is why we can say that oppression is evil.
It is evident to me that rights are not inherent but granted by men to their fellows (and consequently themselves). How can they be inherent in an individual when fundamentally they are about relationships between people?
