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: If that many! I guess this is a lot like that "one drop" rule in the old south. Just one gay marriage will destroy all heterosexual marriages in the whole world!
