Red herring, red herring
First order of business: Please accept my sincere apologies for the hiatus. Unforeseen circumstances kept me away from my beloved Bloody Well Write. But I’m back! (Lesson learned: Be careful what you wish for.)
All kidding aside, on to the topic at hand: What the #%$* is a red herring? I came across this little tidbit via my husband. Of course, my memory being what it is, I can’t remember the exact circumstances, but let it be known that he was the one who gave me the idea for this entry.
I can admit when I don’t know something; I do it all the flippin’ time. And even though I had once known the definition, I hadn’t retained it well enough to say, “Oh yeah, I know what you mean, honey.” So what exactly is a red herring?
Its most organic definition, I suppose, is a fish. It’s a herring that’s been cured by a process of drying, salting and smoking; after the process is finished, the fish takes on a dark brownish color that some people might consider red — maybe because red is more festive. Who knows? But there you go.

Red herring
When my husband used the term, though, he meant a secondary definition: A red herring is something that deliberately diverts attention from the real issue at hand. Its origins are not 100 percent clear, but Wikipedia (good, ol’ Wikipedia) has this to say:
The term originates from an article written published 14 February, 1807 by journalist William Cobbett in the polemical Weekly Political Register. [4] In a critique of the English press, which had erroneously reported Napoleon’s defeat, Cobbett recounted that he had once use a red herring to deflect hounds in pursuit of a hare. In response to the press mistake, Cobbett declared, “It was a mere transitory effect of the political red-herring; for, on the Saturday, the scent became as cold as a stone.”
Red herrings can be found throughout mystery novels, as the bad guy or gal tries to throw the scent onto an unsuspecting passerby or perhaps the hero/heroine of the story. Pollyanna endings usually have the red herrings exposed for what they are — diversions — while the villain sulks off to jail. A bit of karma, of sorts, for trying to fool those who won’t be fooled.
Happy trails!

http://en.wikipedia.org/wiki/List_of_fallacies#Red_herring_fallacies – This is what came to my mind first. While very similar to what you describe, the context is slightly different.
Once you are familiar with these debate “tactics”, you’ll never want to argue politics again… most people use ONLY red herring arguments.
Awesome list. Thanks for posting!
