Recently, I read two journal articles that took a closer look at some of the less ideal sides of human rights, one by wa Makau Mutua from 1996, and one by Sally Engle Merry from 2003, and I believe both of them are still relevant today.
In the end, the existence of human rights is a cause to celebrate, but that does not mean that they are perfect, or that we should not try to constantly improve how we implement them and use them to shape the world.
