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.

Example Input: Comment: Trolling again, Trid?  Sad.
Example Output: Non-identity-attack

Example Input: Comment: Totally agree...he can't accept any blame whatsoever....let's just blame the black guy....as of today:  his OWN REPUBLICAN leaks from the White House are Obama's fault (are you kidding me?) and the botched raid in which a SEAL died last month is the military's (and Obama's, by the way !!!) fault!!
Example Output: Identity-attack

Example Input: Comment: Proof, please. Of course, you have none but you apparently like to make things up as you go.  What color is the sky in your world?
Fact is, we don't know and anyone who thinks they do has their nose so far up Hillary's backside they can't possibly know what's the truth.
Example Output:
Non-identity-attack
