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.
One example is below.
Q: Comment: It's bad enough we already have all these American sicko's living in this country shooting up theatre, schools, churches, malls, etc., we don't have room for crazy muslims.
A: Identity-attack
Rationale: This comment contains identity attacks on both American and Muslim.
Q: 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.
A:
Non-identity-attack
