defense against impugning of character?

[Johnny Eric Williams]

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.zerohedge.com/news/2017-06-21/connecticut-professor-calls-whites-inhuman-aholes-says-let-them-fking-die

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
