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: 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.
Non-identity-attack

Comment: It's funny that when a black person commits an outlandish crime, all black people are implicated by association.  But when a white person commits an outlandish crime, it's just that person and they don't represent all white people. I'm almost 60, raised good, responsible children, contributed to society as a hard worker in several successful careers, and have never been arrested for anything (not even a speeding ticket). Yet, I'm lumped together with these two hoods who robbed a bank simply because they're black and I'm black!
Identity-attack

Comment: I think when Mr. Thompson publicly proclaims his sincere belief that everyone who opposes Trump's proposals personally hates him, his wife, his kids, and his church, then, yes, he may discover that some people will perceive him as 'ignorant.'
