Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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.
Solution: Identity-attack
Reason: This comment contains identity attacks on both American and Muslim.

Now, solve this instance: Comment: I'm commenting directly on the letter... hard to know how I could be much more "on topic" than that!

Is this the topic: "But let a white cop shoot a black criminal, and all hell is to pay." OK, is the letter writer calling Mr. Castile the schoolworker a "black criminal" because he has multiple tickets for speeding and driving without insurance? I think that is a purposeful mischaracterization of someone who seems like a decent guy.

Or this, "One thing is sure, however: White people aren't going to go around shooting blacks because of it." That seems like a naive statement given the history of violence against blacks. One can hope, but "sure"? I'm not sure.

Are the attacks racially motivated? Of course.
