Our society's language about disadvantaged groups matters deeply. It is not divorced from "real" actions taken on behalf of the marginalized because language shapes public perception. Politically incorrect speech cultivates callousness and prejudice in the public consciousness. Statements deemed politically incorrect often involve offensive terminology and ideas that threaten society’s vulnerable members.
The unspoken rules of political correctness prevent such harmful rhetoric from being shared without criticism. Politically correct standards protect disadvantaged people.
Emphasizing the importance of being politically correct gives people an awareness of ideas and words that hurt disadvantaged people. Armed with this awareness, individuals can prevent using their free speech in a derogatory way. For this reason, political correctness is actually an asset to society. It enables people to share their opinions in an unoffensive way, ultimately encouraging the free flow of ideas. Politically correct speech is a necessary facet of any fight for equality.
