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.
Problem:Comment: Funny that you contrarians are never actually able to refute the science involved.

PS. Voting up your own post is considered slightly declasse. But don't worry, there are dimwits aplenty to do it for you.
Solution:
Non-identity-attack
