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.

[Q]: Comment: No, not common knowledge to the vast majority.  It's simply an opinion held by those who fall for the sore loser propaganda.
[A]: Non-identity-attack


[Q]: Comment: It's funny that when a black person commits an outlandish crime, all black people are implicated by association.  But when a white person commits an outlandish crime, it's just that person and they don't represent all white people. I'm almost 60, raised good, responsible children, contributed to society as a hard worker in several successful careers, and have never been arrested for anything (not even a speeding ticket). Yet, I'm lumped together with these two hoods who robbed a bank simply because they're black and I'm black!
[A]: Identity-attack


[Q]: Comment: "students from all backgrounds feel welcome here and they have an identity here,” 

Unless of course you have a gay identity, in which case you are told you "struggle with same-sex attraction," because as we all know, in the Catholic world as in Iran, according to Mahmoud Ahmadinejad to an audience at Columbia University, gay identity doesn't exist.
