Task: Toxic Language Detection
Input (English): Comment: The allegation we should be most careful with is that so-and-so lied.  Amazingly, some people don't know what it takes to prove a lie.  A lie is a false statement, KNOWN to be false by the person who utters it.  John Hobson, a Harvard man, should have learned that in 3rd grade.  

Hobson says of Pandora that she "undoubtedly believes what she writes," but practically in the next breath, says of her: "Pandora lies, and her lies have regularly been shown to be lies." 

Well, which is it?   Does she believe what she says (in which case she cannot possibly be a liar), or does she know the falsehood of what she says and says it anyway (in which case she IS a liar)?  

I mention these things as one who generally agrees with Pandora.  I don't believe she has ever lied, and have only rarely thought she is wrong.  Before one calls another a "liar," he at least ought to know what it means to lie, and it's hard to believe a Harvard man doesn't know.
Output (English): Non-obscene
