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: The sad part is most black people in Baltimore won't do a thing to stop the violence due to being hypocrites. They burned down a portion of the city for a crack dealer (Freddie Gray) when the alleged perpetrators were white, but when black street thugs break into a black US veteran's home and execute him, it's no big deal and just another day in Bodymore, Murderland. No progress will be made until the black community drops the "us vs them" attitude and starts holding their own people accountable for their crimes.
Example Output: Identity-attack

Example Input: Comment: Nope. Converting the rail guideway to a dedicated bus lane would be the equivalent of getting a job at Starbucks after you spend six figures getting a law degree at Harvard.  Our rail system will have a maximum capacity of over 32,000 people per hour per direction, approximately 3x the capacity of the H-1 freeway. It can operate with as little as 90 second headways (40 trains per hour) with each train carrying up to 800 people. Additionally, since it will be driverless, the operating costs will be 20-30% cheaper than an at-grade rail system and 50-65% cheaper than a bus system. BRT systems, like at-grade light rail can carry 5,000-8,000 people per hour per direction and the biggest single operating cost item is the drivers.  Grade-separated high capacity rail systems are hands down the most efficient way to move large numbers of people, but they are very expensive to build (capital costs). If we've already built the guideway, we'd be idiots to run buses on it.
Example Output: Non-identity-attack

Example Input: Comment: Trudeau needs to talk about the millions murdered by Muslims. The fact their religion does not respect human rights.
