That seems methodologically quite questionable for the conclusions drawn. Like many blind semantic analysis attempts which consider language of a crash report for bug testing toxic due to the instances of "does not work", and "kill" and "fail". Meanwhile "I hope you enjoy eating your family then." is positive.

Falsely presenting subjective viewpoints as objective would appear more rational. It isn't the trappings which make it rational or even distance from emotions. One can rationally make "non-optimal" decisions from subjective personal costs.
