Definition: In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: identity-attack and non-identity-attack. Identity attack refers to anything rude or disrespectful about someone's identity, including appearance, race, gender, and sexual orientation.
Input: Comment: One can't please all the people all the time.  The professor represents diversity every bit as much as black Americans do but PC liberals prejudge him and discriminate against his right to free speech.  Would liberals be equally upset over a black professor in white face?   No.
