defense against impugning of character?

Dear cypherpunks, my character has been recently impugned by CampusReform.org's Anthony Gockowski and I find this unacceptable. The impugned allegations are appearing now in two places I have found: http://www.campusreform.org/?ID=9334 http://www.zerohedge.com/news/2017-06-21/connecticut-professor-calls-whites-... Is there a simple mechanism to handle these bigots? I don't mind a legal approach in the courts as that could be an educating experience - but it needs to be something executable in a shorter period of time. Sincerely, John Williams
