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.

Ex 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.

Ex Output:
Non-identity-attack

Comment: People like you are just plain nuts. We can't change what's already taken place and the systems we use right now, but we can alter whats going to happen in the future. If we followed your ideology then we'd still be poisoning rivers and watersheds with raw chemicals and we'd have a dozen more Love Canals. People like you think the status quo is just fine no matter how much damage it does. Burning oil and gas causes us about 15 billion per year in excess health costs from lung and respiratory disease. Instead or praising your almighty pipeline and oil god why not try and look into alternate sources that would reduce (not end) our need for this harmful stuff. 

Actually forget it .... lets just go back and start using DDT and asbestos in large scales ... I mean who needs good health right. I mean why change when it was all so good before. We won't just stop using the stuff but we can stop expanding it's use. Which would you prefer

Ex Output:
Non-identity-attack
