Call for the firing of Professor David Guth who tweeted the next mass shooting should be NRA members children

We all agree the Navy Yard shootings were a terrible tragedy. My heart goes put to the victims and their relatives. I can only imagine the grief they feel. Shortly after this tragedy professor David Guth of the University of Kansas tweeted a message implying that the children of NRA members should be the victims of the next mass shooting. Although I believe in free speech as a parent I am horrified that the university is defending and standing by this professor. Former students rate Mr Guth as a C teacher who ruins the educational experience of his students by shoving his ideas down their throats. Regardless of which side of the gun control issue you take calling for the murder of innocent children is unacceptable....I am calling for the immediate dismissal of Mr. Guth
