Isn't political correctness supposed to be an insult instead of an actual school of thought?

Isn't claiming your insulting phrase is an ideology like claiming dickheads are an ethnicity?

Also, somebody please spoonfeed me about critical theory, Wikipedia just gives me stuff about analyzing and changing society, which seems pretty fucking broad.
