Just hit me as I was composing scathing reposts to the paid deniers over on Richard Black's BBC environment blog.
Unfortunately, the blog is infested with obvious paid deniers/disruptors (obvious if you're trained in spotting them), and it's sad because there are people there trying to discuss and learn. If not blocked, they will eventually succeed in castrating the blog, just as happened to Andy Revkin's "Dot Earth" on the NYT.
Anyway. I'd recently described an organization I know as "an addled loon egg", and may have been heard to comment how glad I am to know that loons are not endangered, in some venues...
And the words just came together. Denial. Loon.
Oh, the fit is perfect, and "denialoon" sounds to me like what is known in the marketing biz as a "sticky" word. It's memorable; and can get around.
So; a little boxing, from me. Denialoons is what they are; and will always be. Much stickier than "flat-earther".
Pass it around! :-)
ps - well, pooh. A quick google, done after writing the above, shows that one other person has put this together, before me. But, they made no effort to launch it. I wanna launch it; good epithets can have legs, or wings, in this case...
