In sociology and political philosophy, the term Critical Theory describes the Western Marxist philosophy of the Frankfurt School, which was developed in Germany in the 1930s. This use of the term requires proper noun capitalization, whereas "a critical theory" or "a critical social theory" may have similar elements of thought, but not stress its intellectual lineage specifically to the Frankfurt School. Frankfurt School critical theorists drew on the critical methods of Karl Marx and Sigmund Freud. 
Critical Theory has been weaponized in the Culture Wars as political correctness. It is the act of criticizing or the intentional gathering of community organizers for public attacking that is directed towards any social institution or social issue, without giving any solution or offering any other alternative in its place. This can be used as a mainstream media Propaganda tactic in order to sway public opinion on any social issue by intentionally demonizing the group or institution, with or without sufficient evidence of the accusations made.
Outrage Culture, Political Correctness
The western value system in the United States has been deeply mired in the effects of the Outrage Culture, building momentum through targeting the youngest minds to enforce classifications of Political Correctness for the purpose of censoring free speech and aggressively shaming people into submission. The orchestration of the plandemic along with the economic devastation of Americans, the utter destruction and anarchy in major cities, informs us of the intended direction of the current globalist agenda. Which is to destroy the American Constitution through spreading hatred and continue to demoralize its citizens in any way that they can, in order to attempt to stage their coup d’état.
The term political correctness is used to describe language, policies, or measures that are intended to avoid offense or disadvantage to members of particular groups in society. Since the late 1980s, the term has come to refer to avoiding language or behavior that can be seen as excluding, marginalizing, or insulting groups of people considered disadvantaged or discriminated against, especially groups defined by sex or race. In public discourse and the media, it is generally used as a pejorative, implying that these policies are excessive or unwarranted.
In the early-to-mid 20th century, the phrase "politically correct" was used to describe strict adherence to a range of ideological orthodoxies. In 1934, The New York Times reported that Nazi Germany was granting reporting permits "only to pure 'Aryans' whose opinions are politically correct."
As Marxist-Leninist movements gained political power, the phrase came to be associated with accusations of dogmatic application of doctrine, in debates between American Communists and American Socialists. This usage referred to the Communist party line which, in the eyes of the Socialists, provided "correct" positions on all political matters. According to American educator Herbert Kohl, writing about debates in New York in the late 1940s and early 1950s,
The term "politically correct" was used disparagingly, to refer to someone whose loyalty to the Communist Party line overrode compassion, and led to bad politics. It was used by Socialists against Communists, and was meant to separate out Socialists who believed in egalitarian moral ideas from dogmatic Communists who would advocate and defend party positions regardless of their moral substance.— "Uncommon Differences", The Lion and the Unicorn.
