Communist countries practice strict control over speech and thought. However, since the 1980s, another form of speech and thought control has appeared in the West. Thought police use the banner of "political correctness" to run amok in the media, society, and education system, using slogans and mass criticism to restrain speech and thought. Even though many have already felt the evil power of it's control, they have not grasped it's ideological origins. Phrases such as "political correctness," together with "progress" and "solidarity," have long been used by communist parties. The hidden implication behind political correctness is to classify individuals into groups according to their victim status. Those who are the most oppressed should, therefore, be accorded the most respect and courtesy. This judgment is rendered solely on one's identity, disregarding individual conduct and talent, is the basis of what's called "identity politics."
