Definition: 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.
Input: Comment: What madness is this that you would give people new reasons not to use the system when in fact what we want is increased ridership? Why would I chance sitting at the rail platform in Golden, CO, for twenty-five minutes waiting for the next departure when I could just spend that twenty-five minutes driving into downtown Denver, instead? Will you compensate us for our lost time, time being money and all.

Is the cost of the system itself the loss leader, or is the cost of running an extra train down it the loss leader? Is this penny-wise pound-foolish? Who cooked this one up, exactly, and what have they got against public mass transit solutions that work?

This seems like sabotage. This seems like an attack on civil infrastructure. Why are we still cutting the nose to spite the face in 2017? This is the 21st century, this irrational self-destructive crap needs to be treated as the immoral civil treason that it always was. Drive them out tarred and feathered. Restore our scheduled runs.
Output:
Non-identity-attack
