Legislative advances in Colombia, since 1991, have created gaps and doubts in the theoretical field, about ethnicity. This is a delicate subject and is of special importance for ethnic peoples, marginalized and discriminated. The essence of ethnicity, in the root as a human being of all individuals is unknown. This essence is rejected and undervalued, rather than being respected and exalted, paradoxically, there are groups working on the denial of the being of the others and put in doubt the selfsame human existence of the different individuals, on questioning the difference, putting into question and turning it into a field of struggle between some people who proclaim themselves as superiors and others referred to them as inferior.
