There is new character called PC principle in new episode。 He replaces the old principal。 And He brings a new culture to the town。 In school, he may make violence or punishment to make students follow his idea。 He hopes to create a world where people can respect each other。 It sounds nice to some extent。 The PC principle represents someone mad about the Political Correctness。 The author tells the audience a political correctness supporter might be someone just graduating from colleague。 As a new force in American society, these kinds of people do not know so much about the world and it’s easy for him to accept the political correctness。 And he also has energy to accomplish it。 But the author indicates that sometimes Political Correctness supporter is not what he looks like。 Some Political Correctness might just pretend to be Political Correctness to show they are progressive。 The real purpose for them may be getting laid with some girls or other advantageous things。The interesting thing is that when the Political Correctness group faces the real minority, they do not know what to do。 They just do what they believe will benefit minorities。 But the minority does not like them at all。 Even the minority prefer to have more freedom to speak。 In the wave of Political Correctness, we can find that there are also some guy who try to take advantage from it。 In the South Park, there is a retarded guy named Nathan。 He knows that a revolution from political correctness will come, what he does is to wait for the best time and get what he wanted。 He is called “speculator” in the real world。  At the end of nineteen seasons, the PC principle declares that he will not away from the South Park。 It actually represents political correctness will last for a long time in the real world。 And the world can no longer ignore it。 Anyway, they represent a new force in American that can no longer be ignored。 No matter he is right or wrong。 The progressive voice should still have his voice。文献综述
