politically correctadj. Abbr. PC
Of, relating to, or supporting broad social, political, and educational change, especially to redress historical injustices in matters such as race, class, gender, and sexual orientation.
Being or perceived as being overconcerned with such change, often to the exclusion of other matters.
Note the second defintion, and let's do a little bit of critical thinking here. What exactly is 'overconerned'? How can you be over concerned with redressing injustice? Who defines what is overly concerned? Is it the same people benefiting from the injustice? And what do we mean by historical? Are we being white about it, and thinking that every ten years we get a do over, and redressing all the wrongs we did in that time period should not be done?
