Detailed Instructions: 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: Most of the shooters are significantly mentally ill. While the guy who shot Giffords (if my memory serves me correctly) was psychotic, he was a white nationalist, who almost always is conservative. (Note white nationalist organizations who endorsed Trump.). But the concept that Dems are violent and GOP supporters aren't is nonsense.
A:
Identity-attack
