Where do human rights come from? Did we have them from when we split off from our closest ancestors? Did they magically appear when someone first thought them up, and they just stayed? Why do our closest relatives not have human rights? You yourself mention that people in Belarus have human rights. Why can the government ignore their human rights then? Why isn't there some magic barrier stopping the government from trampling on the populations human rights?
