Decoloniality or decolonialism is a school of thought used principally by an emerging Latin American movement which focuses on untangling the production of knowledge from a primarily Eurocentric episteme. It critiques the perceived universality of Western knowledge and the superiority of Western culture. However, the culture itself is above the divisions and racial issues. From my personal perspective if we talk about music, it is interrelated and interconnected within different cultures. For instance if you look at the origins of jazz. Not mentioning different painters or singers (i.e. gospel music). On the other hand historically you can look at the Sykes - Picot agreement, which gives you much bigger picture of the historical and political game behind the scene of colonialism. another example could be the creation of Pakistan. Looking from this perspective on the human rights movements it is much more complex.

What “rights” are you referring to? There are two types of rights, innate and man-made. Innate rights are independent of colonization, where man-made rights are dependent thereof. An example of innate rights relative to the physical constructal law:

I would think so. As long as your clarify who you mean by “humans”, and that you mean it in a way that is inclusive of oppressed peoples. For example, children can be overlooked when considering human rights - I believe this was an impetus for the eventual creation of the UN Declaration of the Rights of a Child.
