TASK DEFINITION: In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: toxic and non-toxic. Toxicity is defiend as anything that is rude, disrespectful, or unreasonable that would make someone want to leave a converation.
PROBLEM: Comment: If the Grifter, Liar and Crook in Chief could only shut up and let backroom diplomacy work, maybe, just maybe this headline would be NUL & VOID. He likes the attention and wants to show the world how ignorant and stupid he is.

SOLUTION: Toxic

PROBLEM: Comment: Allan Ross, Trump did not say ONLY
but these are the 6 countries that would most likely affect USA
Trump knows that there are terrorists in Phillipines, Chechnya and other places but they are unlikely to target USA

SOLUTION: Non-toxic

PROBLEM: Comment: There has been anecdotal evidence about a correlation heat and violence (most notably inner city riots) for over half a century.  

This op-ed piece and your abstract (as well four of the other titles in your citation) strike me as the usual background pieces for more research dollars that the R-G publishes on behalf of both OSU and the U of O on a regular basis.

SOLUTION:
Non-toxic
