TASK DEFINITION: In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: insult and non-insult. Insult is any lanugage or act that is disrespectful or scornfully abusive.
PROBLEM: Comment: He had not "taken all measures". We should all know that  if we really cannot miss an appointment, we should schedule our flights to take into account the possibility of flight delays, and not rely on everything going perfectly. 

By the description of the criteria airlines use to decide who gets bumped, chances are he must have bought a really cheap ticket. When you do that, you should realize you increase your chances of getting treated accordingly.

SOLUTION: Non-insult

PROBLEM: Comment: You're stupidity seems to defy logic. You're part of the destructive left-wing. You're entire life is based on lies, normal for you. So you call others opinions a lie only because they differ from yours. Typical socialist thinking.
