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.

Example Input: Comment: Don't most gay guys like getting roughed up by another man?
Example Output: Identity-attack

Example Input: Comment: Once more. What do we owe Mexico? Why do people keep saying that we need to protect Mexico? What have Mexico done for us that we must bend backward to protect that country that exports to us narcotics and illegal immigrants? Please explain.
Example Output: Identity-attack

Example Input: Comment: Rubbish.  Marijuana has been around since the third day of creation.  Please don't give any credibilty to Reefer madness.  Marijuana is far less dangerous than a host of so called legal products.  

A shame you didn't provide a link to that study.  I would have liked to have seen if there were any critical reviews of it.
Example Output:
Non-identity-attack
