A shocking example of the Nigerian Press censorship of the Nigerian Public occurred on the Nigeria Village Square last week (December 14). A runty dude called the "Admin" assumed the role of the almighty god, went on a rampage barring & removing, willy-nilly, comments that he/she deign to be "personal attack" on some almighty Tin gods, who are nothing but loose-lips jeun-jeun [sic] Nigerian journalists on the payroll of some ruling gangsters, on the flimsy excuse of "civilogue" — a word that is yet to find its way to the world-wide-web of dictionaries but only in the imagination of corrupt Nigeria Journalists.

Some media outlets have decided they've had enough of the endless juvenile trolling and hate-mongering, and have either adopted a stricter moderation policy (such as Politics Daily's calling for a "civilogue") or forced would-be commenters to fill out forms supplying information that would make it easier to track their identities and ban them if they run afoul of the site's rules.

But I can do this: I can knock down political nastiness when it presents itself to me. It is time to say "enough." [C]leaning up the mess will not be easy. But it can be done. One polite rebuke at a time. We need a name, of course. I suggest "Civilogues," those whose speech is civil.
It's slightly odd that the coiner of civilogue, Jeffrey Weiss, originally defined the word as a type of person: "'Civilogues,' those whose speech is civil" (see the earliest citation). Fortunately, the more comprehensible and to-the-point "civil dialogue" sense is the one that people now use (helped, no doubt, by seeing that sense in the title of Weiss' article: "Make Our Ugly Discourse Better: Join the Civilogue").
