by your logic we have no rights as everything can be taken away, by death
so you have NO right to earn any money, you have NO right to live, you have NO right to speak to anyone else, you have NO rights
you really want to say that Rights must be inalienable?
now, in my opinion, Rights are the basic things all humans need to enjoy a good standard of life, to get a the job they want and to live in good health, imo we should strive towards making sure everyone has these rights, no matter what there race, nationality or gender.
