In different countries, there are different levels of political freedom among the people. The most important indicator of political freedom is freedom of speech, criticism and protest. Some governments show a more flexible approach to domestic political criticism and protests, while some deal with and suppress them more violently; which are introduced under the title of "dictatorship" or "free government". What is important is that there is no precise criterion and standard for recognizing, distinguishing and classifying dictatorial and free governments. Western countries, through certain organizations and foundations, annually classify countries based on their political and ideological standards and often introduce themselves, their allies and friends as "free countries" in a biased manner and label and introduce their rival or enemy governments and countries as "dictatorships". This article attempts to present a scientific, operational and impartial method for solving this problem. For this purpose, countries have been indexed and classified based on the "scope of criticism and protest", "scope of criticism and protest", "type of criticism and protest", and "type of dealing with and confronting criticism and protest".
