You will be given a definition of a task first, then some input of the task.
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.

Comment: Yes, it's called the Trainwreck Syndrome. I believe Professor Rubbernecker of Johns Hopkins coined the term in 1938 to describe the human tendency of fascination with abnormal behavior.

Anyway, I guess everyone who saw Brokeback Mountain must be gay. No other way to explain it.
Output:
Identity-attack
