TASK 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.
PROBLEM: Comment: I am reminded of Martin Luther King's "Letter From A Birmingham Jail". I am particularly reminded of this paragraph:

We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed. Frankly, I have yet to engage in a direct action campaign that was "well timed" in the view of those who have not suffered unduly from the disease of segregation. For years now I have heard the word "Wait!" It rings in the ear of every Negro with piercing familiarity. This "Wait" has almost always meant "Never." We must come to see, with one of our distinguished jurists, that "justice too long delayed is justice denied."

Substitute "homosexual" for "Negro", and it rings true in this situation.

SOLUTION: Identity-attack

PROBLEM: Comment: Democrat mantra: “If you’re not pro gay…stay the hell away."

SOLUTION: Identity-attack

PROBLEM: Comment: Re: "when you are asked to leave a plane on which you are, after all, only a guest?"

There's a difference between a "guest" and a fully paid customer. Both you and United Airlines should learn the difference. I sincerely doubt when you invite guests over to dinner, you make them pay you for it, and then beat them up after they do.

SOLUTION:
Non-identity-attack
